Polvorones (Mexican Wedding Cakes) - cooking recipe

Ingredients

1/2 cup vegetable shortening
1/2 cup butter (do not use margarine)
1/2 cup sugar
2 large egg yolks, only
1/4 cup orange juice
2 oranges, zest of
4 cups all-purpose flour
powdered sugar, to taste

Preparation

Preheat oven to 400^F.
In a large bowl, beat shortening and butter until fluffy.
Add sugar a little bit at a time.
Add egg yolks, orange juice, and peel.
Stir in flour with spatula.
On a floured surface, roll out the dough to 3/4\". Cut out 2 1/2\" circles and place them on a greased baking sheet. Roll the dough scraps and continue to roll until all the dough is used.
Bake for 25 minutes. Be careful not to overcook them--they are done when they are barely starting to tan.
Transfer to a rack to cool.
Sprinkle with powdered sugar through a fine sieve.
