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 cm in diameter. Brush ropes with lightly beaten egg white, then cut into 6 cm lengths. Dip each in pearl sugar to coat. Place on greased baking sheets and bake at 180ºC 15 to 20 minutes.
