500g cooking apples, after peeling and coring

75ml water
1kg sugar

1. Put the sliced apple and water into the preserving pan.

A seedless version of this jam can be made with small, sour apples or crab apples, in which case do not peel or core the apples, but cut them up and cook them with the water and the blackberries until soft. Then rub the fruit thoroughly through a sieve. Use one pint of pulp to 1lb of sugar and continue as above.

2. Simmer until the fruit is soft and skins disintegrate if rubbed between thumb and finger (make sure it has cooled a little before you do this).
