1/2 lb Butter or margarine

    1/2 c  Sugar

      1    Egg; separated

    1/2 ts Vanilla

  2 1/4 c  Flour

           Pearl sugar
  Beat butter until creamy, then beat in sugar and egg yolk. Add vanilla.
  Gradually work in flour to form dough. Chill. Roll dough out into long
  ropes about 1/2 inch in diameter. Brush ropes with lightly beaten egg
  white, then cut into 2 1/2-inch lengths. Dip each in pearl sugar to coat.
  Place on greased baking sheets and bake at 350F 15 to 20 minutes.
