These are a Christmas classic. My older sister made these in the 1960's...but I'm sure the recipe is much older than that!
1 cup butter
2/3 cup powdered sugar
1 teaspoon vanilla
1/4 teaspoon salt
2 cups flour
1 cup nuts -- ground fine
Mix together butter and powdered sugar. Add vanilla and salt. Mix in flour and nuts. Chill 30 minutes. Shape into small balls and bake 12-15 minutes at 375 degrees. Remove to rack and sprinkle or roll in powdered sugar.
NOTES : Can use black walnuts for a different flavor. Also can roll into small logs and cut into patties.
