Even though I don't like raw onions, these fermented onions impress me more the more I use them. Chop them up and throw in a salad, spread, or sandwich for more probiotic goodness.
Fermenting onions in a salt brine turns onions into a slightly sweet, mildy tart and far less pungent treat to use in cooking or on top of salads. Plus, raw fermented onions don't give the eater the same lingering bad onion breath.
