Pour boiling water over the currants, soak for 5 minutes, drain, dry with kitchen paper and dust with a little flour.
Mix the potatoes, quark, eggs and flour, season with salt and let rest for 5 minutes. Knead in the currants and lemon zest, cut off approx. 5 cm dumplings with a tablespoon, place them on a floured work surface and press them flat and oval with the underside of the spoon.
Do not heat too little clarified butter in a pan and stir-fry the quark pods until golden brown on both sides and keep warm. Serve thickly sprinkled with the cinnamon and sugar mixture.
