Sustainable use of leftovers: onion powder

Who doesn't know it: half onions that are drying in the fridge, or forgotten garlic cloves that are increasingly wasting away. It is not uncommon for people to not reach for the waste container. This need not be! Leftover onions and garlic can be used to make a versatile spice powder without much effort - for seasoning meat, sauces, mushroom dishes or marinades.
