Cut the peaches crosswise and dip them briefly in boiling water. Skin, halve and stone the fruit. Weigh out 600 g of pulp and cut into small pieces. Cut the bananas into 1/2 cm thick slices and squeeze the orange halves.
Mix the banana slices with the orange juice, peach pieces and both types of sugar in a saucepan. Cover and let stand for approx. 2 hours.
Slowly bring the fruit and sugar mixture to the boil while stirring and let cook for approx. 5 minutes. Then roughly puree the jam, pour into prepared jars and close tightly. Then place the jars on the screw cap for 5 minutes and turn them upside down to cool again.
