Traditionally, pickled onions are common in British cuisine, often served alongside fish and chips or pub-style dishes. In Latin American cuisine, you’ll find them on tacos and ceviche. The key to making great pickled onions is choosing the right type of vinegar and balancing it with sweet and savory elements.
