The shape of this cookie is what makes it a horn: you don't need the musical instrument ability to enjoy them. The only music you will hear is mmmmmmmmmmmmm............
Ingredients: 1 1/2 cups powdered sugar, 1 cup butter, softened, 2 egg yolks, 1 1/2 teaspoon vanilla extract, 2 cups all-purpose flour, 1/2 cup ground almonds, 1 teaspoon cream of tartar, 1 teaspoon baking soda, 1 cup chocolate chips, melted, extra powdered sugar for sprinkling.
Preheat oven to 325 degrees. In large mixing bowl, combine powdered sugar and butter. Add egg yolks and vanilla and continue beating. Gradually add flour, almonds, cream of tartar, and baking soda, mixing until thoroughly combined. Shape into 1 inch balls. Roll balls into 2 inch ropes; shape into crescents. Place 2 inches apart on ungreased baking sheets. Flatten slightly with fingers.
Bake 8-10 minutes or until set; cookies do not brown. Allow to cool on baking sheet for 2 minutes before transferring to cooling racks.
Melt chocolate chips in microwave (if too thick, add 1 teaspoon shortening). Stir until chocolate is smooth. Dip one end of each completely cooled horn in chocolate and place on waxed-paper-lined tray. Sprinkle remaining half with sifted powdered sugar. Refrigerate until chocolate is set; then enjoy!
Makes about 3 dozen cookies.
