Knead the flour, 1 pinch of salt, nutmeg, 1 egg, butter in flakes and possibly 1-2 tablespoons of cold water to a smooth dough. Grease a square tart tin (20 x 20 cm). Roll out the dough on a floured work surface and line the mould with it. Refrigerate the base for about 1 hour. Wash the herbs, dab dry, put some aside for garnishing. Pluck the rest and chop finely.

Sauté the spring onions and garlic. Add herbs and vine leaves and steam briefly. Mix 3 eggs, 2 egg yolks, sour cream and milk. Stir in herb mixture. Season to taste with salt and cayenne pepper. Line the pastry base with vine leaves set aside.
