Wineberry jam

Updated on 9 October 2026

• Makes: ± 5 jars of 250 ml
• Time: 40 min
• From: Japanese wineberry

Ingredients

• 1 kg Japanese wineberries
• juice of 1 lemon
• 500 g jam sugar with pectin (2:1)

Method

1. Remove the sepals and stalks and rinse the berries very briefly; they are very soft.
2. Simmer the berries with the lemon juice for 5 minutes, until they fall apart.
3. If you do not want seeds, rub the mixture through a fine sieve and return it to the pan.
4. Add the jam sugar and bring to the boil, stirring.
5. Boil hard for 4 minutes (or as the packet says) and skim off the foam.
6. Fill hot, clean jars to the brim, close and turn them upside down for 5 minutes.

Storing: A year in a cool, dark place; once opened, in the fridge.
