If a sale has you stocking up on onions, but you are afraid you won’t use them all before they go bad try this: Cut the legs off an old pair of pantyhose. Then slip one onion at a time into the toe, knotting the pantyhose after each onion addition. Hang this up inside your pantry. Cut below the knot of the bottom onion each time you need one. Storing onions this way allows air to circulate so your onions won’t spoil or get moldy.
