Drain the chickpeas and collect the liquid. Put the chickpeas aside and use them elsewhere.
Beat the liquid with a mixer. When it starts to get stiff add the powdered sugar and continue to beat until stiff. This will take some minutes.
Now melt the chocolate in a water bath.
Carefully fold a few splashes of lemon juice and the slightly cooled chocolate into the whipped mass.
Pour the mixture into dessert bowls and refrigerate.
For example, decorate with berries before serving and enjoy!
