Preparation

Mix 2 tablespoons flour, 1 tablespoon oil, sugar, a pinch of salt and yeast obtained from 2 tablespoons flour, 1 tablespoon oil and juice in which they boiled potatoes. Spread a sheet and, with a glass, cut round shapes. Put the filling in the middle (walnut, jam) and place the parts on top of each other, in the shape of a crescent. Bake in hot oil until it gets a crust.
