For the nectarine currant jam, grate, sort and weigh the currant. There should be a kilo. Crush the currant, bring to the boil and pass through a strainer to remove the seeds.
Wash and seed the nectarines and add to the currant. Mix everything together with the preserving sugar, blending with a hand blender if necessary until smooth, then cook according to the directions on the sugar packet.
Pour into clean jars with twist-off caps.
Preparation Tip:
Try the nectarine and red currant jam with amaretto instead of rum.
