Put flour, 1/4 teaspoon of salt, butter in pieces and 1 egg in a bowl. Knead quickly to a smooth dough and cover and chill for about 30 minutes. Wash and halve the tomatoes. Roll out the dough on a floured work surface to a circle (approx. 29 cm Ø). Place in a greased tart tin (26 cm Ø) sprinkled with flour, press the edge lightly. Cut off any excess dough.
Wash the chives, shake dry and cut the lower part into small rolls. Mix the ricotta, 4 eggs, chives and milk and season to taste with salt, pepper and nutmeg. Pour the ricotta mixture into the tart tin, spread halved tomatoes on top. Bake the quiche in a preheated oven (electric range: 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 35 minutes until golden brown. Remove the quiche, let it cool down briefly and garnish with chives
Waiting time approx. 30 minutes
