Butterhorns

Dough
2 cups all-purpose flour
1/4 teaspoon salt
1/2 cup cold margarine
1/3 cup cold butter
1 egg yolk, lightly beaten
3/4 cup sour cream

Filling
1/2 cup chopped pecans
1/2 cup sugar
1 teaspoon ground cinnamon

Glaze
1 cup confectioners' sugar
2 tablespoons milk
1/4 teaspoon vanilla extract

In a large bowl, combine flour and salt. Cut in margarine and butter until crumbly. Stir in egg yolk and sour cream; shape into a ball.

Chill several hours or overnight. Divide dough into thirds. On a well-floured surface, roll each portion into a 12-in. circle. Combine filling ingredients.

Sprinkle a third of the filling over each circle. Cut each circle into 12 wedges. Roll each wedge, starting at the wide end. Place on greased baking sheets with points down.

Bake at 350° for 15-18 minutes or until lightly browned. Make glaze if desired. Combine all ingredients and spread on warm rolls. Makes 3 dozen.
