Parmesan Fans

Directions

1. 1
   Cut butter into flour until mixture resembles fine crumbs. Blend in sour cream. Divide pastry into 4 equal parts; wrap each part and refrigerate at least 8 hours.
2. 2
   Heat oven to 350F degrees. Roll each part of the pastry into a rectangle, 12 X 6-inches, on a well-floured cloth-covered board. Sprinkle with 2 tablespoons of the cheese. Fold ends to meet in center, forming a square.
3. 3
   Sprinkle with 1 tablespoon of the cheese. Fold in folded edges to meet in the center. Fold lengthwise in half (as if you were closing a book).
4. 4
   Flatten lightly; fold lengthwise again. Cut 3/16-inch slices on folded edge; place on ungreased cookie sheet. Bring ends together to form a fan shape. Bake until light brown, 20 to 25 minutes.
