This recipe is a traditional cookie from my MIL family. This is from Switerand. Our nickname for these is "diaper cookies". The key to these cookies is that the dough must be handled as warm as possible. It must be done quickly before it cools down. It will harden at room temperature. MIL says absolutely "DO NOT Double this recipe" This should be made 1 month before you want to eat them. They are stored in a tin for a month to soften.
