Here is a easy to make version of the Hungarian Kipfels using a ground walnut filling. I have never tried to use Lekvar or Apricot filling in these, but I may try this year.
2 cups flour
1/2 pound margarine or butter
Cut the margarine into the flour. Add to it, 1 egg yolk and 3/4 cup sour cream. Blend until smooth. Wrap the dough in a floured sheet of waxed paper. Chill at least 4 hours. Once chilled, divide the dough into 3 equal balls. Keep the dough chilled so it is easier to work with. Take one ball out and roll into a large circle. Sprinkle with nut filling. Cut into "pie wedges" Roll up starting with the wide end. Place on greased cookie sheet.
Bake 350 for 20-25 minutes or until lightly golden brown.
3/4 cup chopped nuts
1 teaspoon cinnamon
3/4 cup sugar.
