For the noodle dough, knead both types of flour, egg, 1⁄2 tsp. salt, oil and 80-100 ml lukewarm water with the dough hooks of the mixer to a smooth dough. Form the dough into a ball on a well floured work surface.
Wrap in foil and chill for about 1 hour.
Meanwhile peel and finely dice the onion and garlic. Sort, wash, shake dry and chop the spinach. Heat 1 tablespoon butter in a pot. Sauté onion and garlic in it. Add the spinach and steam for about 2 minutes.
Pour into a sieve and press out easily. Grate the Parmesan cheese. Stir half with ricotta into the spinach. Season to taste with salt, pepper and nutmeg. Let it cool down.
Cut the pasta dough in half. Roll out the two halves very thinly (1-2 mm) in a rectangle on a floured work surface. Spread the filling with a teaspoon as approx. 40 heaps at even intervals on a pastry sheet.
Spread a thin layer of water on the spaces in between and place the second pastry sheet on top. Press the spaces well. Use a knife or a dough wheel to cut the gaps into about 40 squares.
Cook the Schlutzkrapfen in portions in boiling salted water for about 7 minutes.
Meanwhile wash the chives, dab dry and cut into small rolls. Melt 80 g butter in a large pan until golden brown. Remove the Schlutzkrapfen with a skimmer, drain well and toss in the butter.
Season with salt and pepper. Sprinkle with chives and the rest of parmesan.
