Small Batch Blackberry Jam

Plain blackberry jam has a purity of flavour that can’t be beaten, and it doesn’t have the hassle factor of a jelly.

We’re falling in love with the idea and practice of making small batch jams, and this is about as simple as jam gets. Fruit, a splash of water, a little lemon juice and sugar, and that’s it.

I can whip up a couple of pots’ worth this small batch jam on a spare burner while cooking supper: simmer fruit with a splash of water (this stops them catching on the bottom of the pan and burning) until soft and they have released their juice, add the lemon juice and sugar, continue simmering until all the sugar has dissolved then boil quickly until setting point is reached, and voilà, delicious jam.

Bowl of blackberries

This jam is a great way of using a glut of blackberries. As it’s not a strained jelly, yes it does have pips in it, but this means that you can come back from a fruitful walk with a tub full of blackberries, and without the need for giant sized preserving pans or other specialized equipment, whip up a quick batch that evening and fill a couple of jam jars. Jelly although pip free is more of a faff!

The best way of getting hold of blackberries is to find some bramble bushes when out on a walk. Away from any busy road and above the level which a large dog can lift their leg to, and with suitable permissions, and you have the main ingredient for this delicious jam, which will taste all the sweeter when made from foraged; and thus free, food.Bowl of wild foraged blackberries viewed from above

Blackberries on their own have a low pectin content: pectin is the carbohydrate that makes jam jammy and not runny. Without pectin, the fruit would just flow off your slice of toast, which would be no fun at all.

To increase pectin levels in this jam to ensure a set, I’ve added a tablespoon of lemon juice for each jar, and for me, this results in jam of the right consistency; not too runny, but not spoon reboundingly jelly-like either.

Interestingly wild blackberries have more pectin than the sweeter farmed varieties, in general the more sour the fruit the higher the pectin level.  So those berries which are too tart to snack upon will be ideal for making jam – in my bowl above you can see I deliberately picked a few which were under-ripe.

And by using no added pectin the jam just bursts with fruit flavours. However, if you like your jam to have a stiffer consistency, though, then you can use a jam sugar that includes added pectin. That’s one main advantage of making your own home made jam – it can be just as you like it.

I think of jam in terms of ratios, and this jam has the simplest ratio of them all: equal weights of fruit and sugar.

The other aspect of jam that people are sometimes wary of is that of making sure it’s set. For some ideas about this, see our three methods of testing for setting points in our delicious recipe for blackberry and apple jelly. Or you might like our recipe for one pot blackberry jelly!

Simple three ingredient blackberry jam. This easy small batch recipe makes just 2 jars.

Small Batch Blackberry Jam – Ingredient Ratios

  • Equal weights of fruit and sugar
  • 1 tbs lemon juice to every 200 – 220g fruit

How to Make Small Batch Blackberry Jam

A saucepan viewed from above filled with blackberries and sugar

First, wash the blackberries, discard any which are damaged or overripe, weigh them, place in a saucepan, stir in the sugar and lemon juice and leave for an hour or two.

Or if you want your jam in a hurry cook the blackberries with a tablespoon of water over a low heat until juicy, gently squash with a potato masher, then add the sugar continuing to cook on a low heat until the sugar is dissolved.  Then proceed to step 3. 

A pan of blackberries and sugar viewed from above

Second,  once the sugar has drawn out the blackberry juice cook on low heat, stirring frequently to dissolve the sugar. Meanwhile place clean jam jars in a low oven to sterilize.

Third, once the sugar is dissolved, it’s time to set the jam. Increase the heat under the saucepan and bring it to a rolling boil. Check the set by one of the three common methods: the flake test, the temperature or the plate test. I go into more detail about setting points in my post for apple jelly with thyme.

Two freshly filled jars of blackberry jam viewed from above. Once

Fourth, when the blackberry jam has reached its setting point, allow it to cool for a few minutes so the fruit can settle evenly in the jam, then spoon into the jars and seal the lid.

A jam funnel, ladle and glass jug are really helpful here.  Keep the jars in a roasting pan, they very very occasionally crack and the pan will contain the hot sticky mess.

Allow to cool completely – the lids will pop as the vacuum forms in the jar. Enjoy!

This is delicious served on a slice of freshly baked no yeast bread or spread on a slice of fruit loaf. 

Blackberry goes so well with lemon, I like to add a spoon to the bottom of a lemon posset to make it more special.

Ingredients

  • 450 g blackberries
  • 450 sugar
  • 2 tbsp lemon juice ((about a whole lemon))

Instructions

  • Wash the blackberries discarding any which are damaged and place in a saucepan.  Add the sugar and lemon juice and stir.
  • Leave for an hour to allow the sugar to draw the juice from the fruit.  Then heat gently to dissolve the sugar.
  • Once all the sugar is dissolved, quickly bring the temperature up to boiling to set the jam. Test with either a thermometer for a setting temperature of 105C, or another method as detailed in this post.
  • Spoon into sterlized, heated jam jars, seal with lids and allow to cool.

Notes

  • This recipe is 3 Weight Watchers Smart Points for one portion
  • Use the best quality fruit, discarding any over ripe or damaged berries.
  • Wild blackberries have more pectin than farmed. If your berries are especially tart - but still ripe - you can use less lemon juice.
  • 450g of blackberries will fill 2 x 250ml jars or will make just over 2 cups.
  • 450g of wild blackberries is approximately a litre or a generous 4 cups.

    This is a super jam recipe! My mother used to make huge batches of wild blackberry jam in Canada, which is great with all the free wild fruit, but fruit in the UK is expensive and only comes in tiny punnets – so this is a perfect recipe!

    Looks wonderful but I’m curious if I could substitute marionberries? I have over 30 quart bags of frozen berries picked from my Grandmas mammoth 50+year old bushes. I’ve never made jam, but inherited her home with a complete ‘fruit room’ full of canning equipment & am dying to use some of these items. Especially since our first year gardening since moving in didn’t go over very well. Thanks!

    I have used this recipe several times, as I am citric intolerant I do not use the lemon juice and it still comes out wonderful and fruity. Fresh is best, but I have even used frozen fruit in the winter.

    Reply
    • Helen

      So glad you like it. We often make jam from a bag of mixed frozen berries too – so intensely fruity. I’d advise adding a few unripe berries for a better set if you are leaving the lemon juice out for a firmer set.

    It didn’t work for me and I don’t know why! I have blackberry sauce but definitely not jelly. Might have to go picking again and see if I can have a re-do.

    • Helen

      Hi Deborah,

      I’m currently writing a long post on setting point.

      if your blackberries are very ripe then it is harder to get a set. I would add some more lemon juice and / or include some under ripe blackberries. Wild berries have more pectin than the farmed ones.

      You can also include just a little tart apple to help it along too.

      The sauce would be delicious warmed up and poured over vanilla ice cream!

    I used your recipe for first time jam making after foraging 2.5kg of blackberries (only so much crumble you can make). I admit I did double up as I had so many but it came out amazing. I am converted totally as I never realised how easy it is. Just wanted to say thank you.

    Thank you for this wonderful recipe. This is the first time I have made jam and can’t believe how the bramble blackberries are so full of flavour once cooked with the sugar and lemon juice. It is by far the best jam ever… My husband I have been picking them in the lunchtime hour at Acorn Ridge, which is just a few minutes from where we live in the English countryside. If there where 6 stars, you would have them from me.

      Hi Claire, I don’t think it would work at all as the sugar is the preservative. You might need to make a freezer jam instead that will be low carb, and also keep safely,

      Hi Olly, it sounds as if you cooked it a little too long. Sometimes it just happens, even a minute can make the set too hard. If you catch it before you jar it a little extra water can help. I’d try warming one pot of the jam with some water, repot and keep in the fridge.
