Ingredients for pickling onions


Onions: I like to use red onions but you can really use whatever you have on hand. This can be a great way as well to use up onions that are about to go bad.

Vinegar: The vinegar is what makes these babies snap! Vinegar is the key ingredient in pickling. You can really use any type of vinegar here. Each type will give the onions its own flavor.
