Drain the peaches on a sieve. Beat egg yolks and sugar until frothy and the sugar has dissolved. Add curd cheese and poppy seed bake and mix. Whip cream until stiff and fold into the quark.
Puree the peaches with the cutting stick of the hand mixer. Pour the poppy seed curd and puree, up to 8 tablespoons, in layers into high dessert glasses. Pour the rest of the puree into a freezer bag, cut off a small corner and spray onto the dessert in a spiral shape.
Decorate with lemon balm.
