Defrosting the Freezer – so Baked Cranberries
Wednesday August 14th 2013, 7:32 pm

baked cranberries with orange and cardamon

Yes it has been a while since I last posted, so long in fact that I have forgotten how. But that doesn’t mean I’ve been idle. For anyone who doesn’t know already, I do post regularly on facebook so do feel free to like my page and then you can follow what I am up to.

The other day it became imperative that I defrost the freezer. I don’t like my freezer particularly as it is a dumping ground for things I tend to forget about, all the while it is costing money to run. But it does offer a convenient and practical option now and again and I daresay for some foods it is the best way to preserve them. I fill the freezer up with stuff as it is effortless to do so but I prefer bottles on shelves to a forgotten freezer-full, out of sight out of mind. The other day I realised the freezer was defrosting of its own accord, demanding some attention, so I gave it a good clear out, defrosted it, washed it down with bicarb then switched it on all ready to start the process again. There were luckily few casualties, I took the opportunity to edit down the contents, but 2 bags of cranberries, put away last Christmas (or could it have been the year before!) and some redcurrants from last summer had started to thaw so needed using up.

With an abundance of freshly picked summer fruits in urgent need of preserving, these blasts from the past were something I could do without, but there was no way I wanted them to go to waste either. The redcurrants went into a traubleskucha redcurrant cake courtesy of nadel & gabel. The cake was a big success; a light sponge base with a layer of tart redcurrants topped with a macaroon lid that cracked and splintered as the fork went in. I’ll be making that one again and perhaps will add some vanilla or almond extract to the sponge next time too. So highly recommended and you may still find some currants for sale, my local supermarket has them right now.

So that left the cranberries. In the UK, fresh cranberries are only for sale for 2 minutes round Christmas time. Last year Sainsburys sold Kent grown cranberries but only in selected Kent stores. Otherwise they are always imported. I’m sure I’ve seen them all year round for sale at the farm shop down the road that sells frozen fruits loose from big tubs, that you can buy by weight by the scoopful. I haven’t had cranberries enough to really develop a love for them .. till now anyway.

For inspiration I decided to refer back to one of my all time favourite books, an American book I have mentioned before, Fancy Pantry by Helen Witty (1986) and her recipe for baked cranberries with orange and cardamon is a triumph. You can eat it like jam or a compote, it is somewhere between the two, and it is the easiest preserve you will ever make, requiring no bringing to setting point. The flavour is fresh and amazing and even though it is out of season, I am wolfing it down and planning the next batch. Eat it as an accompaniment to savoury dishes too, in the same style as a traditional cranberry sauce. It isn’t overly sweet, it’s just right. The sugar content is not high enough to make a preserve that will keep, so best store in the fridge, if it lasts that long, or do what I do and water process (can / bottle) it so it will keep on the shelf for a year or more.

baked cranberries with orange and cardamon

BAKED CRANBERRIES WITH ORANGE AND CARDAMON

Makes approx 5 x 250g (half pint) jars

600g (1lb 5oz) cranberries
1 large seedless orange
500g (1lb 2oz) white sugar
1/8 tsp ground cardamon (seeds removed from pods and freshly ground)
60ml (4 Tbsp) water

Pre-heat the oven to 175C /350F /Mk4. Spread the cranberries in a ovenproof glass dish (I used 2 square Pyrex baking dishes). Remove the peel from the orange and pull away and discard the pith from inside and any surrounding the flesh. Chop the orange and peel roughly and blitz it in a blender or food processor to make a pulpy puree.

Pour the puree, sugar, cardamon and water over the cranberries and mix everything together. Cover the dish with foil and bake in the oven for 30 minutes. Lower the temperature to 160C / 325F / Mk3, remove the foil and bake for a further 50-60 minutes, turning the mixture over with a spoon every 10-15 minutes. The cranberries will look slightly translucent and be surrounded by syrup.

Spoon the hot preserve into hot sterilised jars and seal, or alternatively process them in a boiling water bath for 10 minutes. Remove from water bath and leave till cold before testing the seals.

Landlove magazine feature

I’ve got 6 pages in Landlove magazine this month. The magazine isn’t available online so until it is off the newstands, you will have to buy a copy to read it. I’m really pleased with the feature and I think it captures the spirit of what preserving is all about for me.



CANNING FOR BEGINNERS WORKSHOP AND MEAL
Tuesday February 26th 2013, 5:12 pm

canning for beginners workshop

Our London canning event is now just days away. There are a few tickets still remaining so you still have the opportunity to learn about canning and bottling, how to stock your own pantry and then make fabulous meals inspired by your glorious comestibles.

To book your ticket, follow the link here. I will be bringing along an assortment of my own preserves, pickles and relishes so we can enjoy matching flavours and coming up with the perfect combinations. Kerstin and I will be preparing a banquet from jars. I would love you to be as inspired by food in jars as I am.

More information about canning and the event in my last blog post here.

JAM JARS & MARMITE
Monday February 28th 2011, 2:27 pm

vintage French jam jars filled with damsons

This is supposed to be a quick one, but in true geek style has become something more. Inspired by Kerstin Rodger aka MsMarmiteLover trailblazer and proprietor of the first underground supper club in the UK, whose blog post at The English can Cook about her love of jars and forthcoming supper club event this Friday Jar Food – Pickles, Potions and Preserves , got me thinking about …. jars. Seemed like a quick blog post to gather some of my favourite jars together, without it becoming some big deal would be a possibility. Trouble is, that when the differences in ridges on glass are something you admire, you get sort of, caught up. Anyway, here are just a few from my collection and I hope you enjoy them as much as I do.

vintage French jam jars filled with fig jam

Vintage French jam jars are such classics and feature plenty of ridges and facets in all sorts of variations. A good heavy handful and chunky lipped edge are what you want. A few nibbles around the top are OK too. You can always use them as candle holders and vases if you don’t have any confiture to fill them with. I will be selling some of my vintage French jam jars at the Selvedge Spring Fair on the 2nd April in London. Follow link for more info.

vintage Ball canning jar with angelica

When I wrote Fruits of The Earth my preserving book, (sorry currently out of print but will be available again in paperback in June) the publisher asked me to use some Ball jars, to suit the American market. They are virtually impossible to buy here in the UK but by one means or another, I’ve acquired a few along the way. These vintage ones in beautiful turquoise glass look great when used as vases.

Wye Valley Fruit vintage English jam jar

I always look out for interesting shaped jars and my vintage English Wye Valley Preserves jars (I’ve got 2 of them) are real favourites. They just wouldn’t make them like that these days. Finding them was sheer fluke, so sorry no tips on where to look. Just keep your eyes peeled.

vintage Ball bale jar with wire top

Another Ball canning jar, this time with wire bale clip top. These aren’t recommended any more for canning but people do still use them. Finding new rubber seals is the problem. See the brilliant Food in Jars for more info about this.

Ball canning quilted jelly jar

I love Ball quilted jelly jars and again you can’t buy them in the UK. My friend Chris brought me 2 back from the US a while ago and I use them repeatedly. They are so cute and worth looking out for if you are in the States.

vintage Kilner Improved preserving jar

I’ve been given quite a few old Kilner jars by people. Often I’m given them because their owners think them now redundant but in fact you can still buy replacement seals for them. Peter Denyer at The Kilner Jar knows everything there is to know about Kilner jars, sells the seals and also reconditions the rusty tops. A real niche business. These Kilner Improved jars are great because they have a glass lid. For canning, there is something really satisfying about only natural materials, glass and natural rubber, being used here. Look out for old jars on your local Freecycle.

Weck flasks for canning cordials and fruit juice

Weck jars and flasks have such simple lines and are great for the modern pantry. Again, just glass and rubber used here and they work so reliably. I’m a big fan of canning cordials and syrups and find the 1/4 and 1/2 litre size flasks most useful. Weck jars are really easy to open as you simply pull the rubber tongue to release the seal. Also seals are reusable.

vintage Kilner 70s jars for bottling

With great 70’s style, these vintage Ravenhead Kilner jars are another favourite that I use a lot. The screw bands were made in orange, red and brown plastic, and also white apparently, but I’ve never seen one of them. Again try The Kilner Jar for replacement seals. The last canned jar I tried to open was so well sealed that I had to email Peter Denyer for advice on how to prize off the lid. In true expert fashion, he told me to carefully slide a knife under the seal and gently lever. You have to be careful when doing this as chipped edges can totally ruin a canning jar and make it unusable.

Kerstin’s Jar Food supper club is one NOT to be missed. Also her book Supper Club – Recipes and Notes from The Underground Restaurant is available to pre order on Amazon and will be published at the end of March.



CULTURE CLUB – HOMEMADE YOGURT
Tuesday January 18th 2011, 6:25 pm

yogurt for dessert with pear butter and squashed Blaisdon plums

2010 was the year I learnt about canning, or bottling, or hot water processing stuff in jars, whatever you want to call it. Following the year through ingredients, working with the seasons and the produce that was close to hand, has given me a real feeling of connection to the food that I eat and has changed my life and my approach to preserving. Not only that, I’ve got a cupboard full of food in jars, a sort of mini pantry, as my house is too small to include a special room or larder. Granted, most people don’t have shelves of bottled comestibles in their sitting room or lined up on the sideboard! See my friend Tigress’s recent post about her pantry ( the Domestic Goddess is sooo last century, now chatelaine in the buzz word!) and Dana and Joel’s great wall of preserves, in their city apartment. So you see it isn’t necessarily about having a special room in your house or living in the country.

*From now on I am going to refer to the bottling and preservation of ingredients using a hot water bath process as ‘canning’. You’ve been told. I know that in the UK this causes some confusion as the assumption is that this infers putting food in tin cans, but I am talking about preserving food in glass jars. OK have we got that straight now?

The biggest surprise for me has been how amazing the flavours of canned food can be. I grew up thinking that only fresh was best and that bottled, tinned and stored foods were second rate and down market. What I have learnt during my first canning year has totally blown that notion out of the water.
Now the year has swung full circle and there is a feeling of beginning again, its time to take store and note the successes – the rhubarb ketchup, black grape chilli jam and lemon fig & lavender marmalade I want to always keep a stock of. But more importantly I want to plan my goals for the year ahead. Plant blueberry bushes on the allotment to produce enough fruit to preserve, thus bypassing those ridiculously expensive and tweeny-weeny cartons you get in the supermarket, and too plant an asparagus bed so that a few years hence I will be able to harvest my own crop.
It is about pacing things, their needs to be a correlation between the amount of food stored and the rate it is consumed. There will always be some experimentation going on, but as well as enjoying the satisfaction of a well stocked cupboard I love the moment the spoon scrapes the bottom of the jar, each empty jar offering the opportunity to be filled anew. In the year ahead I will be using my preserved foods as ingredients for baking and to include as part of other delicious meals.

It's easy to make yogurt at home

As well as jams and chutneys, I’ve got cordials, compotes and fruit purees and pickles stacked on my shelves. Today for lunch I popped open a jar of salted caramel pear butter and another of squashed Blaisdon plums. A dollop of each plus some homemade yogurt (and a tiny sprinkling of hazelnut praline on the top just to be flash) made a really delicious snack. The important thing about these preserves is that they aren’t laden with sugar in the same way that jam usually is. This is why canning makes such sense.
Sorry! This post was supposed to be about making homemade yogurt, but it has changed into something else. I’ll do the yogurt thing later as it seems a strange diversion to go there now and I’ve got other things I need to get on with. Anyone picking this up by Googling will be well annoyed.



FESTIVE APRICOTS, CRANBERRIES & BOOZE
Sunday December 05th 2010, 1:06 am

dried apricots golden sultanas and Amaretto - the raw ingredients

Month twelve, the very last Tigress’s can jam canning challenge and for December the ingredient chosen by the wonderous Tigress herself, who set the whole ball rolling in the first place, is dried fruits in all their jewelled and seasonal glory. Must admit, apart from chutneys, don’t think I’ve ever used dried fruits in my preserves so this is new for me.
Yet again Fancy Pantry by Helen Witty, my all time favourite book, provided the inspiration. Her dried apricot & amaretto conserve sounded just perfect to meet the criteria of this months challenge, though I’m not a fan of adding alcohol to my jams. Well I say I’m not, that should be, I wasn’t. Over the last year I have discovered how a little splash of kirsch takes sour cherries from quite nice to amazing. Likewise a spoonful of calvados added to apple butter, or some Cointreau poured over squashed plums can take mundane to magnificent, adding something not necessarily consciously alcoholic but that somehow completes the balance of flavours in a wonderful way.
This did mean I had to shell out for a bottle of Amaretto, the down side of acquiring a stock of liqueurs, they don’t come cheap. Thankfully, this jam turned out even better than expected, really special in fact, so now I’ve got plenty of the ingredients left to make more of the same to give as presents. I added fresh cranberries to my jam which are great not only for their flavour and seasonality but for the lovely colour they bring. After I’d made the jam and started to think what it would go well with, ‘warm croissants’ absolutely shouted out to me.

a festive preserve - Apricot, Cranberry and Amoretti jam

I have opted for bright orange sulphured apricots over the darker unsulphured variety for my jam because I can’t bear the thought of starting out with dark brown fruit. It doesn’t bode well in my mind, brown fruit can only get doomier as it cooks, and for a special holiday preserve you want to push the boat out a bit. This preserve could take even less sugar that I used. I did a sugar test on it using a refractrometer and found that it contained 57%. For a preserve to store well without canning, it should be nearer to 65%, so if you aren’t into canning and want to be sure this jam will store in the pantry for any length of time without worrying it will go mouldy, I’d advise you to up the sugar content from 450g to 600g, but taste wise it doesn’t benefit from it. The added alcohol will also help to act as a preservative. This jam tastes so good it most likely wont hang around long enough anyway. If you are not into canning, this should make it obvious why canning is so brilliant. You can preserve using less sugar so the overriding flavour of your jam is the fruit it contains, not sugar. Preaching over, here’s the recipe.

jam with croissant for breakfast

APRICOT, CRANBERRY AND AMARETTO JAM

Makes approx 1.4Kg (3 lbs) jam

225g (8oz) dried apricots
150g (5 1/2oz) golden sultanas or raisins
0.90 ltr (3 1/2 cups) water
225g (8oz) fresh cranberries
1 1/2 tsp grated orange zest
0.25ltr (1 cup) freshly squeezed orange juice
2Tbs freshly squeezed lemon juice
450g (3 cups) sugar
3Tbsp Amaretto liqueur

Chop the apricots into small evenly-shaped pieces. Place them in a bowl with the sultanas and pour over 0.75ltr (3 cups) water. Leave to soak overnight.
Next day, prepare the water bath, jars and seals ready for canning. For more info about how to hot water process, refer to the guide here. Place the cranberries in a pan with the remaining water and simmer gently for 15-20 minutes until the fruits have popped and are cooked through. Leave to cool slightly, then add all of the remaining ingredients (including soaking liquid) except the Amaretto.
Stir to dissolve the sugar and once it has, turn up the heat to a rolling boil and bring the jam to setting point (took me about 10-15 minutes), that is when a dollop on a cold plate readily forms a skin that wrinkles when you push your finger over the surface. Remove from the heat and leave to cool for a few minutes then stir in the Amaretto. Pour into hot sterilised jars, seal and process for 10 minutes. Remove from the water bath and leave till completely cold before testing the seals and labelling.

IT’S A WRAP

Well that’s it. A whole year of the Tigresscanjam completed and wow, it has been amazing. I intend to write another post soon to round up what I’ve learnt and how it has changed my approach to preserving. Thanks to dearest Tigress for taking the time to not only oversee the challenge and the monthly roundups but for asking me to take part. To think that this experience could have passed me by …. well what can I say, how foolish I would have been without that gentle nudge.
I have found all you other canjammers participating truly inspiring. Thanks to all of you for helping me learn so much. As well as introducing me to Meyer lemons, Concorde grapes and Seckel pears, ingredients I will no doubt spend the rest of my life trying to experience first hand, amongst other things, too many to mention here, I’ve got over a few hangups I had about American-isms (and Canadian-isms if there is such a thing) such as ‘canning’. We are of course divided by a common language and as the only Brit taking part, I hope that you’ve likewise picked up some of the flavour of our approach to ‘bottling’ here in the UK. – Love G x



BLACK CHILLI JAM – WHOAH!
Sunday October 17th 2010, 9:58 am

chilli pepper growing

Month ten Tigress’s can jam canning challenge and for October the ingredient chosen by Kaela at Local Kitchen is chili peppers and all things capsicum. I admit, when the October ingredient was revealed, I wasn’t a gal who could tell a jalepeno from a habanero, but another month, another brilliant opportunity to explore and find out what chillis are all about and to recognise what’s hot and what’s not. As luck will have it, I didn’t have to go very far from home to do my research as growing chillis and peppers seems to be a very popular thing these days, so several friends right on my doorstep have provided the raw materials. With a greenhouse or polytunnel at your disposal, capsicums are a seemingly easy crop to cultivate. You can also grow chillis as potted plants on a windowsill.

sweet black peppers growing in the greenhouse

As is always the way each month, I read every recipe I could find for inspiration. With its orangy-red transparency flecked through with tiny pieces of red pepper, chilli jam holds a dazzling attraction for me, but as Morgy, next door, had given me a big bowl full of black grapes, from the vine that scrambles over the front of his rustic shed abode, I decided to use them to form the main carrying jelly for my hotter ingredients. If you haven’t got a supply of fresh grapes you could extract the juice from apples instead or I imagine that bought grape juice would work too.
The other main ingredients came for free as well; sweet red peppers plus a purple one from my friend Shelley’s greenhouse, cayenne chilli peppers grown in the Taurus market garden. Cayenne peppers are only moderately hot, you could tell this as some little creature had been eating them in the greenhouse, chewing away at the stem end and leaving the pointy ends intact. I guess this to be a mouse called Miguel, wearing a sombrero and playing maracas. It goes to show that one end of the chilli is hotter than the other and that mice round here are made of stern stuff.

a selection of sweet red peppers and chillis

So, after extracting the black juice from the grapes this jam was starting to take a different course from the norm. I remember ‘experiencing’ a sculpture once at Tate Modern by Anish Kapoor. It wasn’t a particularly amazing looking piece, just a box painted black and slightly taller than a person. As you stepped up to a line drawn on the floor and looked within, it suddenly felt as if you were about to fall into a void or abyss and the feeling was so strong and unexpected that it made you recoil and say ‘whoah’ out loud. Anyway, that’s what this chilli jam is like, a sticky homage to that Anish Kapoor work, a jam so black when you peer into its dense glossy richness you have to hang on in case you fall through into an alternative jammy universe.
It’s not so hot it blows your socks off, but you can add more heat if you know that’s what you want. I’ve been eating it on bread with cream cheese and it’s really good. I knew immediately that it would be ideal for adding to meat stock to make a fruity gravy with a chilli kick. This is a strange instinctive feeling to have as a non meat eater of many years standing, so I have given jars away to a couple of carnivore friends to try. I’ve already had a request for 6 more jars

BLACK GRAPE CHILLI JAM

Makes approx 6 250g (1/4 pint) jars

2Kg (4.4 lbs) black grapes, whole with stems removed
350ml (1 1/2 cups) white wine vinegar
juice of 1 lemon (50ml / 1/4 cup)
1 clove of garlic, peeled and roughly chopped
300g (0.6 lbs) (approx 5) sweet red peppers, de-seeded and roughly chopped
100g (0.2 lbs) (approx 5) cayenne chilli peppers, de-seeded and roughly chopped
1 tsp salt
1Kg ( 2.2 lbs) sugar
1/4-1/2 tsp of dried chilli flakes

Place the grapes in a pan and heat gently till the juice begins to flow. Once there is plenty of juice surrounding the fruit simmer for 20 minutes, stirring from time to time to make sure it doesn’t catch on the bottom of the pan and squashing the fruit with the back of the spoon. Pour the grapes into a jelly bag suspended over a bowl and collect the juice that drips through, leaving it to drip overnight. The next day measure the juice collected. (You can also put the pulp that remains in the jelly bag through a food mill and use the de-seeded grape flesh you collect to add to another preserve.) I collected 700ml (3 cups) of juice but if your amount is different to this adjust the other ingredients accordingly.

Prepare the water bath, jars and seals ready for canning. For more info about how to hot water process, refer to the guide here. Put the peppers, chillis and garlic clove in a food processor with half of the vinegar and blitz it thoroughly to a smooth sauce consistency. Pour into a preserving pan along with the grape juice, lemon juice, salt, remaining vinegar and chilli flakes. (Another way to adjust the heat would be to include some of the fresh seeds from the chilli peppers instead of using dried flakes.) Bring to a simmer and cook through for 10 minutes then remove from the heat to cool slightly.
Add the sugar and stir over a gentle heat until the sugar is completely dissolved, then up the heat and bring to a rolling boil until it reaches setting point and a small dollop on a cold plate quickly forms a skin when you push your finger over the surface (it took me about 20 minutes). Turn off the heat and leave for 10 minutes, then stir to distribute the chilli peppers evenly through the jam. Pour into hot sterilised jars, seal and process for 10 minutes. Remove from the water bath and leave till completely cold before testing the seals and labelling.
As this is a jam with good acidity and sugar levels, it should keep well without processing so long as you follow the usual guidelines regarding care taken sterilising jars. If you do can it you are making doubly certain that your jam will be preserved safely for a year or even longer.

BOTTLING TOMATOES & THE ACIDITY CUSP
Monday August 16th 2010, 1:05 pm

black cherry tomatoes in a miniature colander

Month eight Tigress’s can jam canning challenge and for August the ingredient chosen by the inspired and inspiring Julia is tomatoes. My relationship with this ubiquitous fruit has been a checkered one. I hated tomatoes as a kid but learnt to tolerate them later on. I do like them as a sauce for pizza, applied with a lightness of touch though. I can now eat cherry tomatoes raw and, like biting into any fruit, appreciate their sweetness so I suppose you could say I’ve made progress.
But it is as objects of beauty that tomatoes especially come into their own. The resurgence of interest in growing heritage varieties has brought all these wonderfully coloured tomatoes to the fore; striped, heart and pear shaped, shaded like a shop display of lipsticks, from gold to chocolate. They are all so fantastically photogenic and worth growing for looks alone.
As an ingredient for canning, they are on the acidity cusp. Tomatoes require special attention for bottling safely using the water processing method or else should be pressure canned. They are only just on the acid side of neutral and acidity can vary for different varieties, so it is necessary to add a little more acidity in the form of lemon juice or citric acid to make sure they stay safely putt. It is important that time spent preserving has a very definite pay off later so it makes sense for me to bottle really useful tomato passata-type sauces for cooking up further down the line into pizza toppings, pasta sauces or as additions to winter casseroles.

pink heartshaped tomatoes

Each year I begin the growing season with high hopes for an extensive range of weird and wonderful tomato varieties. I don’t have a greenhouse so can only grow toms out in the open. We’ve had two consecutive years of blight bringing these plans to a soggy and disappointingly diseased halt, but this year the weather has been kinder. Tinned tomatoes are as cheap as chips, so I don’t think it is really cost effective to bottle tomatoes unless you have your own homegrown supply or you are able to mop up someone elses glut. The plants I have growing in the garden are still some way from the ‘glut’ stage. Thankfully my neighbour Jane has a greenhouse as well as green fingers. She sells her excess garden produce from her garden wall. Last week I picked up four generous punnets of yellow and red tomatoes from the wall and dropped my payment into the honesty box provided.

homegrown cherry tomato varieties

So first a basic tomato sauce. These cherry tomato varieties are as sweet as anything though perhaps not the most ideal kinds for bottling. For sauces, larger fleshy varieties like Roma and San Marzano are good. Skinning so many tiny fruits was definitely out of the question for starters. Tomatoes can be very watery, which means that they will require considerable cooking to reduce, thicken and intensify the flavour, unless some of the liquid is removed first.
In order to give a fresher flavoured result with less cooking time I began by slitting each fruit and removing the seeds by running my thumb quickly through their middles, collecting the seeds in a sieve placed over a bowl. Any collected juice would come in handy later. After a brief cooking time of 10 minutes the de-seeded tomatoes were then processed using a passata mill, running it through several times to separate the skins from the pulp. The passata mill is a bit of kit I acquired some years ago when dreaming of a bounteous tomato crop that never materialised. The mill has sat unused in its box ever since so this was its first opportunity to prove its worth. I must say that I wasn’t too impressed. Passata-ing the tomatoes was a messy and annoying business (compounded by trying to take photographs at the same time). Tomato juice splattered all over the place and possibly it was my fault, but juice was squirting out the handle side as well! Next time I will most likely use my regular food mill over a bowl, which though still requiring patience would be less messy and more controllable. Depending on the scale of the project, to remove skins and any stray seeds you could simply push the tomatoes through a sieve if you prefer. Still too watery for my liking, I strained the flesh again briefly in a sieve collecting more juice to add to what had been collected earlier. 2.5Kg (5 1/2lbs) of tomatoes resulted in 775g (1 3/4lbs) puree and 750ml (1.3 pts) of juice.

HOW TO BOTTLE TOMATO PUREE

Prepare the water bath, jars and seals ready for bottling (canning). For more info about how to hot water process, refer to the guide here.
Put the pureed tomatoes in a pan and simmer for a short time to reach a consistency that suits you so excess juice has evaporated. If the puree is already thick enough simply bring to boiling point. I added 1 tsp sea salt (a non essential, so add salt to own taste or leave out all together) plus an aditional acidic booster. As a general guide you need to add one of the following to every 500ml (1 pt) tomato puree: 1Tbsp lemon juice or 1/4 tsp citric acid. I used balsamic vinegar instead, adding 2 Tbsp balsamic vinegar per 500ml (1pt) puree.
Place a basil leaf inside each jar against the glass and fill jars with tomato, leaving headspace required for your type of jar. Remove bubbles from sides of jars using a small spatula, wipe rims clean and seal. Process 500ml (1 pt) jars for 35 mins and 1ltr (quart) jars for 45 mins. Remove jars from water bath and leave till cold before testing the seals. Any jars with loose seals will require reprocessing or you can keep them in the fridge for using up within a few days. Remember to label all your jars before storing them.
My tomatoes made 2 x 350g (12oz) jars of sauce plus a bit more that I had with pasta for my dinner that evening.

WHAT TO DO WITH THE JUICE

It seemed a shame to waste the lovely sweet juice collected whilst extracting the tomato puree, so I decided to turn it into tomato jelly. You could flavour tomato jelly with fresh ginger and ground coriander or finely chopped chilli. After much deliberation I eventually chose vanilla and white pepper for a jelly with a sweet / savoury crossover. This jelly is delicious on sourdough toast with cream cheese and I used it to fill tiny savoury pastry cases, topped with sour cream or crumbled goats cheese for a really exquisite little mouthful.
As tomato juice is lacking in pectin, a boost in the form of the addition of lemon or apple juice is helpful. Having bottled some whitecurrant juice several weeks earlier to use at times like this, I added some of that for its setting quality. Preserving sugar containing added pectin could also be employed here. Adjust proportions to suit what you have available.

TOMATO, VANILLA AND WHITE PEPPER JELLY

750ml (1.3 pts) tomato juice (a byproduct of making the puree above)
550g (1 1/4lb) sugar
Juice of 1 lemon or 150ml (2/3 cup) whitecurrant juice
1 vanilla pod, split and seeds scraped from inside
1/2 tsp ground white pepper

Prepare the water bath, jars and seals ready for canning. For more info about how to hot water process, refer to the guide here.

Pour the juice through a jelly bag, collecting the juice in a measuring jug. To every 600ml (1 pt) juice add 450g (1 lb sugar). Place all the ingredients in a preserving pan. Stir constantly over low heat until the sugar has dissolved then turn the heat up to bring to a rolling boil. Boil to setting point, (it took me about 10 minutes) when a blob of syrup on a cold plate will formed a skin when you push your finger over the top of it. If using a jam thermometer it will register 220F 105C. Remove the vanilla pod and fill hot jars, leaving the required headroom for their type. De-bubble the sides using a small spatula or chopstick, wipe jar rims clean, before sealing and placing in the hot water bath. Process for 10 minutes, remove from the bath, then leave till cold before testing the seals. Label and store.

tomato jelly tarts served as a canape topped with sour cream

The ratio of sugar to juice is the classic one used when making jellies. This jelly is very nice indeed but I will be tempted to cut down on the amount of sugar when I make this next. It is often safe to keep jams and jellies without hot water processing (canning) them. If you do can them you are making doubly certain that they will be preserved safely for a year or even longer.
