Halve the melon and remove the seeds. Use a ball cutter to cut out small balls or dice the pulp. Put the melon, except for something to decorate, into dessert bowls
Stir mascarpone, quark, icing sugar, vanillin sugar and lemon juice until smooth. Spread half the cream on the melon. Sprinkle Amarettini on top and drizzle coffee over it. Spread the rest of the mascarpone cream on top. Chill for about 1 hour. Decorate the tiramisu with the remaining melon and almonds
