How to make
Beat the egg whites well along with the powdered sugar, add the vanilla and finely ground walnuts.
A sticky dough is kneaded from all the products.
Oval walnut balls are formed, which are the size of a walnut and they are rolled in the coarsely ground walnuts.
Bake the wonderful walnut cookies at 340°F (170°C) for about 12-13 minutes.
