Wash the blackberries.
Place the fruit a batch or two at a time in boiling water. Let water return to the boil, then boil 1 minute. Get fruit out right away, and put in a covered bowl or pot to keep warm. Repeat until all fruit has been blanched.
Put the Clearjel in a very large pot along with the sugar, if using sugar. Mix. Add water (or juice) and food colouring if using, and liquid stevia if using instead of sugar. Stir constantly over medium heat until mixture gets quite thick and begins to bubble.
Add lemon juice, cook one additional minute. Fold in the berries carefully all at once just until evenly mixed.
Fill piping hot mixture into hot jars.
Ladle into half-litre (1 US pint / 16 oz) jars or 1 litre (1 US quart / 32 oz) jars.
