The amount is designed for 8-10 plastic ice cream molds of 50 ml each (e.g. from Ikea).
Wash the strawberries, remove the greens and briefly puree for 3 seconds in a small bowl with the hand blender. I didn`t puree it completely smooth because I wanted to have small pieces in the ice cream.
Beat the cream with the powdered sugar and vanilla sugar until stiff. Fold half of the whipped cream into the pureed strawberries and mix the other half with the banana juice. Now pour the mixture into the molds as you like. I started with the strawberry cream, filled it halfway and then filled in the banana cream last.
