Put the apricots in a pot with plenty of boiling water and blanch for 2-3 minutes. Remove the apricots, rinse with cold water and peel the skin. Remove stones and cut the flesh into pieces.
Wash the cherries, remove the stalks and stone the cherries. Mix 2 tablespoons of sugar with the Gelfix. Put apricots, cherries, Gelfix and cloves in a pot and mix well. Bring to the boil over a high heat while stirring constantly.
As soon as it is bubbling, add the remaining sugar. Bring to the boil again while stirring and let it boil fizzy for 1 minute. Remove the cloves and skim the jam if necessary. Pour hot jam into the jars using a preserving ring and close them immediately.
