My sister is currently raising money for her trip to Tanzania next summer. One event she had to do lately was set up a stall at a fete. As chief jam maker of the house, it was way of contributing. Problem was there were no berries for picking and the jams I had from last year were gooseberry, bramble jelly and apple jelly, all packaged in Bonne Mamen jars (you can’t sell it in a branded jar) and quite old with goodness knows what growing under the lids… It was the perfect time to dig out all of the plastic bags and yoghurt pots containing mixtures of fruit that had been shoved inside the freezer as they were ‘too much effort’ to go picking through. A mixture of raspberries, blackcurrants, gooseberries, strawberries, jostaberries and tayberries went in the pot together and ended up with something pretty edible and with a wonderful name I found online – ‘Jumbleberry Jam’. I only made 15 jars and my sister sold 11 (15 and a half, I got to keep and eat the half jar as a cook’s perk). The blackcurrants dominated the mixture along with the raspberries – just as well as those are two of the best jams in the world!
I am a jam enthusiast. First it was raspberry obsession, then I discovered blackcurrant, homemade plum (shop ones are always disappointing), bramble jelly, apple jelly, gooseberry, boysenberry and of course strawberry. I would love to try making strawberry jam one year but there is no way I will manage to harvest enough this year. We have been eating them fresh every evening and I need at least 1kg for a couple of jars worth – I will have to shelve that fantasy for the time being and stick to making raspberry and allowing myself the occasional indulgence of buying strawberry jam from Sainsbury’s.
I must admit, I am famous for making runny jam that doesn’t set, even when I add bottled pectin from the shops. However, I think I have worked out how to do it now: do not be impatient about boiling (get on with another job in the kitchen and keep an eye on it rather than standing around waiting), do not be afraid of using lots of lemon juice and use bottle pectin, especially when making jam with berries low in pectin or fruit that has been frozen (they lose some pectin that makes the jam set). The Jumbleberry jam set very well – too well, it was solid and only just spreadable, but after experience I would say most people prefer very set jam to the kind of jam that runs off your toast and goes everywhere but inside your mouth.
This is the perfect recipe for anyone who has old fruit hanging around in the freezer to clear out to make way for this year’s pickings. Enjoy!
(Makes enough for 4 medium sized jars)
- 1 kg mixed berries and currants – 1 kg granulated sugar – Juice of at least 1 lemon, three is best or more – Half a bottle of — pectin
- In a large plan, place the fruit and turn it on to high flame. Add the sugar and lemon juice and stir in until the sugar has dissolved. Bring the mixture to a rolling boil, stirring now and then.
- Place a china plate in the freezer in advance for the pectin test.
- Allow the fruit to boil furiously for more than ten minutes, stirring occasionally to see how it is going. When the mixture starts to feel slightly gloopy and sticks more to the spoon without looking as runny as it did before when it drips off, remove the plate from the freezer and add a dollop onto the surface. Place it back in the freezer for a couple of minutes then take it out and run your index finger through the middle. If the jam is set and wrinkles where you push your finger through, it is ready. If it does not, continue to boil until it does so.
- Once done, turn off the heat and pour in the pectin, stirring it in. Leave the jam to cool.
- Preheat the oven to 150C and sterilise the jam jars and the lids inside – they are done when they feel hot to the touch. Remove these from the oven and allow them to cool.
- Once the jam has cooled slightly and so have the jars, ladle the jam into the jars, place a wax disk over the top if you have any and put the lid on top, using a damp cloth to clean up any spillage running down the sides. Place the jars overnight in a cool place. They will be ready for eating the following day and should last for months.
