The Food Network offers a recipe for sweet koulourakia by Stamie Koutouzis. The recipe calls for butter, sugar, eggs, baking soda, baking powder and flour. Pulp-free orange juice and vanilla extract are also included for flavor.
Preheat an oven to 350 degrees Fahrenheit. Cream 3/4 pound of room temperature butter in a large mixing bowl for about five minutes. Add 1 1/4 cups of sugar to the butter, and continue beating for five to seven minutes. Add 2 eggs, and continue to beat until incorporated. Add 2 tablespoons of pulp-free orange juice to the mixture along with 2 tablespoons of pure vanilla extract.
Combine 3/4 teaspoon of baking soda with 1 1/2 teaspoons of baking powder and 1 cup of flour in a large bowl. Slowly stir in the egg and butter mixture, and gradually add 1 1/4 cups of flour. Stop mixing when the dough comes together, no longer sticks to the sides of the mixing bowl, and is soft and pliable.
Using a meatball scoop, cut balls out of the dough and roll the balls out into long ropes. Fold the dough ropes over in half, twist, then set on a greased baking pan. Beat 2 eggs in a bowl and brush the cookies with the beaten eggs to glaze. Bake the cookies at 350 degrees Fahrenheit for about 25 minutes until they appear golden.
