Cut the butter into pieces. Mix butter, flour, 1-2 tablespoons cold water, 1 egg and 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 about 30 minutes
Peel and wash the carrots and cut or slice them lengthwise into thin slices. Simmer the carrots in boiling salted water for 3-4 minutes, remove, rinse in cold water and drain
Clean, wash and cut the spring onions into rings. Heat oil in a pan. Steam the spring onions for 2-3 minutes while turning, season with salt and pepper and remove.
Mix 2 eggs and cream, season with salt, pepper and nutmeg. Grease 8 tartlet cups with lift-off base (approx. 12 cm Ø). Form the dough into a roll and cut it into 8 equal pieces. Roll out the dough pieces one after the other on a floured work surface, round and thin. Line a mould with the dough, press down the edge and cut off any excess dough
Distribute the carrot slices in a ring in the moulds. Spread the spring onions on the tartlettes and pour the egg mixture over them. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) for 15-20 minutes until the egg mixture has set, then remove and allow to cool for 3-4 minutes
Reduce oven temperature (electric cooker: 125 °C/ circulating air: 100 °C/ gas: see manufacturer). Separate 1 egg. Place the egg yolk in the middle of a quiche, in the carrot ring. Whisk the egg white, also in the middle with a tablespoon, around the egg yolk (the egg white is not completely used up, use it for meringue for example). Repeat the process with the remaining eggs and quiches. Bake the quiches in the oven at the above temperature for 6-8 minutes until the egg has set. Wash the chives, shake dry, cut into fine rings
Waiting time approx. 10 minutes
