One of the customs of Purim is to make a cookie called a hamentashen. They are named, in Yiddish, for Hamen, the villian of the Purim story. The name translates to Hamen's ears but they are also said to be in the shape of his triangle hat.
1 cup sugar
1 cup oil
4 cups (approx) flour
2 tsp baking powder
1 tsp vanilla
1/3 cup orange juice
Preheat your oven to 350º. Mix ingredients in the order listed. Add flour until the dough doesn't stick to the bowl. Chill the dough for an hour or so (overnight is fine too). Roll the dough out on a floured surface. Press out circles using cookie cutter or inverted cup. Place filling in center and pinch sides up to make three corners. Bake on parchment for 30 minutes or until bottoms are browned.
Bete'avon! (that's Hebrew for enjoy!)
