Put the meringues in a plastic bag and crumble them with your hands or a rolling pin. Whip the cream until stiff, fold in the meringue crumbs, chopped chocolate and brittle, put in the freezer and freeze for at least 6 hours.
Turn the frozen mass onto a plate (put the freezer container in hot water for a short time), cut into slices or cut out balls with an ice cream spoon, arrange on a dessert plate and serve with hot fruits, which can be sweetened and / or pureed as desired.
