Peel a ripe mango and an orange, remove the stones and put all the flesh in a saucepan.
Now weigh the amount of fruit. To do this, you either weigh the empty pot beforehand and remove the weight or you cut the fruit into a bowl beforehand. Then you add a corresponding amount of preserving sugar. For example, add 100 g of sugar to 300 g of fruit and puree the mixture with a hand blender.
Bring to the boil on the stove while stirring. When it simmered, let it boil for another 3-4 minutes and make a jelly test. Pour hot into a clean jar, close with the lid.
