It is best to take overripe bananas, as they already have a certain sweetness of their own. Chop the bananas either by hand or with a food processor. The same applies to the marzipan paste.
Stir in the lemon juice and add the preserving sugar to the saucepan. Before turning the stove on, stir the mixture well. Bring to the boil and let it simmer for 3 - 4 minutes. Then pour into the prepared glasses.
I chose 2: 1 as the preserving sugar - if that`s too sweet in combination with the marzipan, you can also use 3: 1, but then the amount of sugar changes (follow the instructions on the package).
