What each ingredient does
- Blackberries
- Supply the main fruit flavour, colour and juice for the pickle.
- Best vinegar
- Adds sharp acidity that gives the pickle its tang and helps preserve it.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar.
The step that matters
Boil the mixture hard for 10 minutes. A hard, sustained boil dissolves the sugar fully and drives off some water, concentrating the liquid so the flavour is balanced and the pickle is more stable for bottling.
