1 Work the quark, salt, oil, egg, egg yolk, flour and baking powder to a smooth dough, cover and put into the fridge for 30 minutes.
2 Wash and sort the spinach, put into a pan dripping wet and heat until it collapses. Drain in a sieve, squeeze out and chop.
3 Peel and dice the onion and sweat in butter until translucent. Press the garlic onto the onion, add the spinach, season with salt, pepper and nutmeg and cook gently for a few minutes. Then leave to cool.
5 Knead the dough on a floured work surface, then divide into 8 pieces and form into small pizza bases. Lay on a greased baking tray and press up at the edges. Top with spinach and mozzarella. Make a depression in the middle of each and break a quail’s egg into it. Bake in a preheated oven (200°) for about 20 minutes.
