A delicious way to take advantage to the bumper crop of wild blackberries this year. Blackberries on their own can be a little flat when made into jam. Adding some elderflower cordial gives it a lovely zing. I made mine using blackberries from my garden and elderflower cordial I had made earlier this summer.
Jam sugar has added pectin, which is needed for making jam with soft fruits, such as strawberries, raspberries and blackberries.
A sugar thermometer is extremely useful when jam making. A good one will have the jam setting point marked on it, making it easier to tell when the jam is ready.
This jam definitely gets better with age, if you can resist, lay it away for a couple of months for the flavours to develop.
