For the dough, mix flour with salt and press a depression in the middle. Add 1 egg and 125 g butter in flakes. Quickly knead to a smooth dough and wrap in foil. Chill for about 1 hour
Clean, wash and cut the leek into pieces of about 1 cm. Melt 1 tablespoon butter in a pot, add leek and braise for about 5 minutes
Roll out the dough on a floured work surface. Cut out 4 circles (approx. 14 cm Ø) and place them in 4 greased, flour-spread Tartelett moulds (approx. 12 cm Ø), pressing the edges together
Whisk 2 eggs and cream. Season to taste with salt, pepper and nutmeg. Wash the chives, shake dry, except for something to garnish, cut into small rolls and add to the egg-cream
Spread the leek on the dough and spread the egg cream over it. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) for approx. 30 minutes. Remove from the oven, let it rest in the moulds for approx. 10 minutes and carefully remove from the moulds. Arrange the vegetable cake and garnish with chives
Waiting time approx. 1 hour
