Knead 200 g flour, 2 egg yolks, 3 tablespoons cold water, 1 level teaspoon salt, 1 pinch sugar and 100 g butter in flakes to a smooth dough.
Roll out the dough between 2 layers of baking paper if necessary (approx. 30 cm Ø). Place the dough in a greased, flour-spread tart tin (e.g. with a removable base; 26 cm Ø). Prick the base more often and chill for about 1 hour.
Finely grate the cheese. Peel and chop the garlic. Wash the chives and cut into small rolls. Mix everything with cream cheese and 4 eggs. Season with salt, pepper and a little nutmeg.
Sprinkle the bottom with breadcrumbs. Spread grated cheese on top. Sprinkle with cheese glaze. Bake in a preheated oven (electric oven: 200 °C/circulating air: 175 °C/gas: see oven manufacturer), on the lowest shelf for approx. 50 minutes.
Remove, let it cool down. Garnish as desired with crème fraîche, flowers and chives.
