For the strawberry-peach jam, wash the fruit, remove the seeds and cut into pieces. Add the preserving sugar, Cointreau and citric acid.
Leave everything covered in a cool place for about 24 hours. Then puree the mixture and bring to the boil for about 5 minutes. (Make a jelly test).
Fill the jam into clean jars while still hot and seal immediately.
Preparation Tip:
Instead of Cointreau, you can also use another liqueur for the strawberry-peach jam.
