Make dough same as for Wiener Kipfel. Roll it out quite thin on a well-floured board and let it rise. Cut also into triangles (before you cut them, spread with melted butter). Mix one cup of chopped fresh walnuts with one cup of brown sugar, juice of a lemon, or grind the nuts; add cream to make a paste, sugar to taste and flavor with vanilla, and fill the triangles with the mixture. Take up the three corners and pinch together tightly. Set in well-buttered pans and let them rise again and spread or brush each one with melted butter. Bake a light brown.
