Mexican Wedding Cookie Recipe
From foodfreeway.com

Ingredients:
1 1/2 cups butter, at room temperature
3/4 pound powdered sugar
1 egg yolk
1 teaspoon vanilla
1/2 cup finely chopped almonds
3 1/4 cups all-purpose flour

Preparation:
Beat butter until light and fluffy, then beat in 2 tablespoons of the sugar, egg yolk, vanilla and almonds. Gradually add flour, beating to blend thoroughly. Pinch off pieces of dough the size of large walnuts and rolls between your palms into round balls. Place 1 1/2 inches apart on ungreased baking sheets; flatten each ball slightly.

Bake in a 275F oven until very lightly browned (about 45 minutes). Let cool on baking sheets until lukewarm.

Sift half the remaining powdered sugar onto a large sheet of wax paper. Roll each cookie gently in sugar. With your fingers, pack more sugar all over cookies to a depth of about 1/8 inch. Place cookies on wire racks and dust generously with more powdered sugar; let cool completely. Store in airtight containers, layer between sheets of wax paper. Makes 3 dozen.
