Knead the flour, butter, milk and a pinch of salt to make a shortcrust pastry. Cover with foil and let rest for 30 minutes in a cool place. Then roll out the dough and line a round, buttered tin with a diameter of approx. 30 cm.
Whisk the sour cream, egg yolks and egg together, season with salt and pepper. Mix in the cut wild garlic and distribute the mixture on the dough.
Sprinkle with flakes of butter and bake in the preheated oven at 200 ° C (top / bottom heat) for about 30 minutes. Cut into pieces and serve hot.
