I made a version of Momofuko's famed crack pie a few weeks ago and to do so had to buy powdered milk. The pie turned out great, but it left me with a package of powdered milk and no ideas on how to use it up. Can anyone explain to me what powdered milk does in a recipe? I know that it can be used as a substitute for milk with water, but what does it add to a recipe that already has plentiful milk in it? What would be some thoughts about how to incorporate it into other recipes without giving them that yucky, fake taste? For instance, mixing it with yogurt or butter... help!
