The procedure is: Blend butter and cheese in a bowl. Slowly add cream. When mixed, stir in flour. Chill overnight or for 2 hours. Roll dough out quite thin. Then mix finely chopped walnuts, sugar and cinnamon. Put a teaspoon of this mixture into each square cut from the dough. Roll from corner to corner and shape into a horn. Brush tops with yolk. Bake at 350 degrees for 15-20 minutes.

The question is how much of a rising ingredient do I need to use? Hope one of you bakers can assist me on this. This was a family favorite.
