Who doesn't know it: Half onions drying out in the fridge, or forgotten garlic cloves that are increasingly withering away. Reaching for the waste bin is often the result. But it doesn't have to be! Onion and garlic leftovers can easily be turned into a versatile spice powder - for seasoning meat, sauces, mushroom dishes, or marinades.
