In my continuing quest to find good uses for blackberries - well to be honest we got stuck on the apple and blackberry cordial which works so well and popular with the non-drinkers of the family, I haven’t done much else, but I have made a bottle of blackberry liqueur (recipe)
It’s pretty good. A martyr to the cause, I have tried it freshly made, and tried it after some weeks. I have tried it topped up with white wine (recommended) and plan to try it in mulled drinks come winter. It’s a tough job but someone has to do it.
