Lentz Sugar Cookies

I shudder to write this but: use margarine. Someday I need to figure out how to make this recipe work with butter, but for now, due to chemical reasons I don't quite understand, butter just doesn't work the same. So, use margarine, and hope at some point I get the time to figure out why. This recipe is by weight. I imagine if you have bought a Kitchenaid, you have a scale, too, because you're a baker. Bake by weight. Thank me later.
