In the summer I picked and froze loads of home grown blackcurrants and blackberries, ( well I didn't actually home grow the blackberries but they do border one side of the allotment and I did pick them!), and as we do not have that many desserts I decided to make some jam, well, jelly, actually. I did make some in the summer and it was gorgeous. I haven't made jam/jelly from frozen fruit before but I checked it out on the internet and it seems that you should just add some fruit with pectin like a cooking apple.
It was very easy to make, 1.1kg of mixed fruit, I used blackcurrants and blackberries, 2 apples (chopped, core as well ) 600ml of water and 450g of sugar to 600ml of juice.
Simmer the fruit and water until fruit is mushy. Strain through a muslin bag into a bowl, preferably overnight. Do not squeeze or the jelly will be cloudy. Add juice and sugar to a preserving pan and bring to a rolling boil for about 5 mins. Test for setting and finally ladle into jars. Voila! Hedgerow jelly. Here is a batch I made earlier!!!
