Wash the limes and lemon. Peel them. Cut out the soft fruit, but remove all the white pith, and cut into small pieces.
Peel and grate the ginger.
Place the pieces of fruit, zest and ginger in a saucepan, add water and bring to the boil.
Fold in the jam sugar and stir while simmering for 5-10. Do a “jam test” to check the consistency is right.
Pour the jam into sterilised jars. Seal and store in a cool place.
