Light tea biscuits

Grind sugar, butter and 2 egg yolks into foam. Add flour mixed with baking powder, a pinch of salt and strong foam of 2 egg whites. Pass the dough through special molds attached to the meat grinder and shape different shapes. Lubricate the metal sheet (tray) with oil, sprinkle with flour and put the products on it. Bake the cookies at a low temperature until lightly rosy, and sprinkle vanilla sugar on the table before serving.
