How to make
Beat the butter along with the sugar, until a white mixture is obtained.
Add the egg, ground walnuts, flour, water and vanilla.
A hard dough is kneaded, which is rolled out into a 0.2″ (0.5 cm) thick crust.
Cut out the cookies with crescent shaped cookie cutters or with a cup of your choice.
Bake the walnut cookies in a greased with butter baking tray in a moderately heated oven.
While they're still warm, the walnut cookies are rolled in powdered sugar and vanilla.
