This is an old recipe from my Mom's dad's side, the origins of which we are unsure. All we know is, they are addictive! Unlike traditional Polish and Czech pastries by the same name, these are tiny open-ended jam cookies. They are traditionally eaten at Christmastime. This is my mom's version of the recipe, so I must warn you from experience that if you double it, you will actually have more of a quadruple recipe!
