Bramble vinegar
Place the bramble blackberries in a bowl and cover with vinegar. Put a plate on top of the mixture and a heavy object on top of the plate and push down lightly.
Leave for 3-5 days.
Stir every day.
Uncover and give the mixture a stir. Then, pressing down with the back of a ladle or spoon, carefully mash the berries to release their juices.
Next, sieve the mixture into a large saucepan, left with the liquid.
Add the sugar to the liquid, stir and heat until boiling.
Simmer for 15 minutes and then simply pour into sterilised bottles.
Keep for a few months and then enjoy in the winter.
