Grate the cheese roughly. Knead flour, butter in pieces, half cheese, 1 egg and 1⁄2 TL salt first with the dough hooks of the hand mixer, then briefly with your hands to a smooth dough. Grease a tart mould (26 cm Ø) with a removable base and dust with flour.
Roll out the dough on a little flour and make it round (about 30 cm Ø). Line a mould with it, prick the base several times. Place the mould in a cool place for about 30 minutes.
Dice Kabanossi and fry in hot oil for 3-4 minutes. Wash the asparagus, cut off the woody ends generously. Steam asparagus in little boiling salted water for about 3 minutes. Drain.
Pre-bake the tart base in a preheated oven (electric cooker: 200 °C/circulating air: 175 °C/gas: see manufacturer) for approx. 15 minutes. Wash the thyme and put something aside for garnishing. Chop the rest. Whisk cream and 3 eggs.
Stir in the rest of the cheese. Season with thyme, salt, pepper and paprika. Dab the asparagus dry and spread on the pre-baked base with the kabanossi. Pour egg cream over it. Bake at the same temperature for 30-40 minutes.
Garnish with thyme.
