Last week we picked 2Kg of blackberries, which made 2pints of strained juice...just over 4 jars of Bramble Jelly.
Then today I had another 2 Kg of blackberries but I made 2.5 pints of juice as I squeezed the jelly bag out. According to Hugh Fearnley-Whittingstall in this article squeezing will not change the flavour, just the clarity. It's not going in any show - just on a scone with loads of clotted cream, and as far as I can see it still looks quite clear any way. So from now on I will squeeze!
