Hedgerow jelly is lovely. You make it with a mix of whatever you can find, as long as it includes crab apples for set. You might find rowan berries, blackberries, rosehips, sloes, elder berries, wild raspberries - whatever your area has. Boil them all together with enough water to cover, strain through a jelly bag, measure and add 1 lb sugar for every pint of juice. Makes a lovely dark jelly.
I made rowan berry and apple jelly which is a lovely soft pinkish red but has an odd taste which is definitely an acquired one. I love it now, but someone has to eat it! Goes well with curry - cools it down.
