Chef Tip: Store Onion Ends in Freezer for Use in Stocks & Broths
Do you ever feel wasteful after you peel and chop an onion, and have to throw away your onion ends? Throw 'em in the freezer in a ziplock freezer bag and use in bone broths, meat broths and soup stocks. When you take out the bones and herbs, take out the onion ends, too. You don't even have to peel, and definately don't thaw them. Just throw 'em in as is.
