Cut butter into pieces. Knead the flour, 1 egg yolk, 1 egg, butter, 1 tablespoon crème fraîche and a pinch of salt first with the dough hooks of the hand mixer, then with your hands to a smooth dough. Wrap the dough in foil and chill for approx. 30 minutes
Roll out the dough on a floured work surface 2-3 mm thin and cut out 5 circles (approx. 14 cm ∅). Knead the rest and cut out another 3 circles. Grease 8 tartlet moulds with lift-off base (each approx. 12 cm ∅) and line with the dough. Press the dough at the edges, cut off the protruding edges and prick the dough several times with a fork. Place the ramekins on a grid of the oven. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) on the lower rack for approx. 10 minutes
Grate cheese. Mix 250 g crème fraîche, starch, 1 egg yolk, 2 eggs and paprika powder. Season with salt, pepper, nutmeg and stir in 3/4 of the cheese. Remove the tartelettes. Spread the cheese mixture evenly in the moulds and sprinkle with the remaining cheese. Bake the Tarteletts at the same temperature on the middle shelf for another 20 minutes
Wash the chives, shake dry and cut into fine rolls. Remove the Tartelettes from the oven, let them cool down and remove the moulds. Arrange the Tartelettes on plates and sprinkle with chives. Serve with salad
Waiting time approx. 45 minutes
