Ingredients

• 1 lb cooking apple, peeled and diced
• 1/2 cup water
• 2 tablespoons lemon juice
• 1 lb blackberry
• 1 1/3 lbs sugar (21oz)
• 3 tablespoons blackberry liqueur (optional)
• 1/2 tablespoon butter

Instructions

1. In a heavy-based saucepan or preserving pan, bring the apples and water to a boil. Simmer 5 minutes until soft.
2. Add the lemon juice and blackberries; cook 5 minutes.
3. Add the sugar, stirring until dissolved. Add the butter and bring to a rolling boil; boil rapidly 15 minutes.
4. Test setting point by dropping a little onto a chilled saucer; if the surface wrinkles when pushed, it’s set.
5. If not set, boil a little longer and test again. If it still doesn’t set, add 1 tbsp lemon juice and boil another 3–5 minutes.
6. Add liqueur if using. Skim off scum with a slotted spoon.
7. Cool 15 minutes, then fill into sterilized jars and seal.
