What I Did With the Remaining Hamentash Dough

There's always going to be leftover dough.
Here's a recipe/strategy/modality that works for many (though not all) doughs.

Sugar Batons

Any amount of cookie dough, pastry dough, or bread dough
Egg wash
Sugar

Roll out the dough and brush the surface with egg wash (I used egg whites since this dough recipe used the yolks).  Sprinkle liberally with sugar and fold over.
Brush the top surface with egg wash and sprinkle with more sugar.
Slice the dough into ribbons and twist each ribbon into a spiral.
Bake at 350 for about 10 minutes.
