One Pot Blackberry Jelly

Come blackberry season this one pot blackberry jelly is a great way to preserve those delicious woodland flavours. Making this jam isn’t an all day process; it only takes a few minutes to pick about one litre of blackberries, and then about 30 minutes turning it into a wonderful pot of fresh tasting preserve. This yields about one 300ml jam jar, or 320g of jelly. It’s the ultimate expression of small batch preserving.

You don’t need specialist equipment to make this jelly. A saucepan, a sieve or colander and a tea towel or similar cloth is about it. A jelly bag is useful but absolutely not essential. One of the great things about making jelly is that you don’t need to worry about the fruit settling out  in the jars, only the set point.

I love making preserves from foraged and thus free fruit.

Tips for Foraging

When you forage make sure you’ve got all required permissions before go. I avoid picking blackberries from hedges next to busy roads, and always pick above the height a dog can reach, but wherever I’m picking, long trousers, a long-sleeved top and leather gloves are useful to minimize scratches from brambles.

The great advantage of making this jelly from foraged and thus free, wild berries rather than buying cultivated ones is that the smaller, less sweet wild varieties have more pectin than the large, sweet commercial varieties.  We usually deliberately pick a few under ripe ones too as they are packed with pectin which will help the jelly set.

Why Small Batch Preserving

We are total converts to small batch preserves – I went preserving mad about 10 years ago; it is SO addictive, and made enough to last us for a decade!

• Small batch means you need no special equipment to make jams and jellies
• Small batch means you use fewer ingredients so can experiment more with techniques, ingredients and flavours without wasting too much when it goes wrong
• Small batch preserves come to setting point faster so that are quicker to make – you can easily make a few jars in less than an hour
• By making less jam you eat (and gift) it quicker so you don’t need lots of storage space – unlike chutneys – jams generally don’t improve with age
• The more batches you make the better you become at making jams and jellies so the more you will make.  preserving is addictive!

How Do I Make One Pot Blackberry Jelly?

First, pick your blackberries. You’ll need about a 450g / one lb or a litre in volume.  A plastic tub of M&S chocolate mini-rolls full is almost exactly right.  If needed, wash the blackberries and discard any that are over ripe.

Second, pop the blackberries in a saucepan with a teaspoon or water and cook over a low heat until the fruit is soft. You can help things along with a potato masher.

Third, strain off the blackberry juice. If you do have a jelly bag, use that, but it’s not necessary. Just line a colander or sieve with an old tea towel, fill with the cooked blackberries and let the juice drip out.

Leave it for 12 hours or so – overnight is perfect. As always, don’t squeeze or poke the bag/tea towel or you’ll get cloudy jelly. To speed things up you can gather up the corners of the cloth pop a bulldog clip on them and then hang over a bowl.

Fourth, measure how much juice you have, transfer to a large saucepan and add three-quarters of this weight in sugar. Also add 1 dessertspoon of lemon juice per cup of juice.

Fifth, heat the mixture over a low heat to dissolve the sugar. Put a clean jam jar in the oven, and set it to about 100°C/220°F/Gas Mark 1.

Sixth, once the sugar has dissolved, turn up the heat to make the blackberry jelly set. Once the jelly has reached a rolling boil, skim off any froth, and start testing to see if its reached a setting point. The high levels of natural pectin in blackberries, along with the added pectin from lemon juice, mean that this is a relatively easy jelly to make. Once it has reached setting point allow to cool for a few minutes.

3 ways of testing jelly setting points

1. The temperature test. Really accurate electronic jam thermometers are readily available, and not expensive. They are much easier to read than traditional jam thermometers. Heat the jelly to the setting point, stir to eliminate any hotspots and recheck.
2. The wrinkle test. Place a couple of side plates in the freezer before you add the sugar. Once the jelly is boiling, start testing by placing some on the plate. Allow it to cool on the plate; when you push your finger through the jelly, you’ll see it wrinkle up ahead of your finger. This technique takes a bit of practice.
3. The flake test. Take a spoonful of jelly from the pan and turn it vertically to tip out the jelly. If the jelly runs off, it hasn’t set. If, however a little remains on the spoon in a sort of wide drip that doesn’t fall, then the jelly is ready. Again, this works best with some practice.

Finally, transfer to the jam jar (a jam funnel helps here), and seal with the lid.  It rarely happens but occasionally the jar can crack, I always stand my jars in a roasting tin once filling, just in case.  Allow to cool fully. If you have any excess jelly, spoon it into a small bowl for immediate enjoyment.

2. Strain through a jelly bag or muslin lined sieve for at least 1 hour, and preferably overnight

3. Weigh the juice.  Transfer to a saucepan and add 75% of this weight in sugar. Place a jam jar in the oven, set to 100°C/220°F/Gas Mark 1
   

4. Gently heat to dissolve the sugar, then rapidly boil to setting point 105°C. Test for setting with one of the techniques listed above.

Recipe Notes

• I only lightly wash foraged blackberries if needed.
• When spooning hot jelly into jam jars, a wide jam funnel is a real help.
• I always stand jam jars in a baking tray when filling them. In the unlikely event that the jar cracks, it means that I'm not faced with jam going everywhere.
