These super easy pickled red onions are a versatile condiment perfect for sandwiches, burgers, or anything else that needs a tangy kick. They are simple to make and can last a while in the refrigerator.
The ratio for the pickling liquid is 2 parts water to 1 part vinegar. Heat the liquid (water, apple cider vinegar, salt, sugar, and chosen herbs/spices like peppercorns) until it is steaming. While the liquid heats, add the thinly sliced red onions to a clean jar. Once the liquid is steaming, pour it over the onions in the jar. The onions will gradually turn a vibrant pink color. For the best flavor, allow the pickled red onions to sit overnight in the refrigerator before serving.
