Ingredients:

* ²/³ cup parve margarine or butter
* ½ cup sugar
* 1 egg
* 1 tsp vanilla
* 2½-3 cups sifted unbleached all-purpose flour
* 1 tsp baking powder
* Dash of Salt

Method

1. Cream the shortening with sugar. Add egg and continue creaming until smooth.
2. Add the vanilla. Stir in the sifted flour, baking powder, and salt until a ball of dough is formed. (A food processor is excellent for this).
3. Chill for 2-3 hours, or overnight
4. Preheat oven to 375 degrees F.
5. Taking ¼ of the dough, roll out on a lightly floured board to a thickness of ¹\8 inch. Cut into 2-inch circles. With your finger put water around the rim of the circle. Fill with 1 tsp poppy-seed or nut filling and fold into three-cornered cookies. (Press two sides together, and then fold the third side over and press the ends together.)
6. Bake on a well-greased cookie sheet 10 to 16 minutes, until the tops are golden.
