Cut the vanilla pod lengthwise and scrape out the pulp. Mix mascarpone, quark, sugar, vanillin sugar and vanilla pulp to a smooth mixture. Wash the currants and dab dry. Put 4 small panicles aside for decoration. Pluck the currants from the panicles and carefully fold them into the mascarpone mixture.
Pour into a piping bag with a large perforated spout and pour onto four wafers in a wave shape. Place the rest of the waffles on top and press down gently. Dust with icing sugar. Decorate with currant panicles and lemon balm
