PREPARATION:
- Preheat oven to 350°F. Grease cookie sheets; set aside.
- Beat cooked and raw egg yolks in medium bowl until smooth. Beat in butter, powdered sugar and vanilla. Stir in 1 cup flour. Stir in additional flour until stiff dough forms.
- Place dough on sheet of waxed paper. Using waxed paper to hold dough, roll it back and forth to form a log; cut into 18 equal pieces. Roll each piece of dough into 8-inch rope, tapering ends.
- Shape ropes into wreaths; overlap ends and let extend out from wreath. Place wreaths on prepared cookie sheets. Refrigerate 15 minutes or until firm.
- Beat reserved egg white with fork until foamy. Brush wreaths with egg white; sprinkle with decorating sugar. Bake 8 to 10 minutes or until light golden brown. Remove cookies to wire racks; cool completely.
