Pickled onions are a food item consisting of onions pickled in a solution of vinegar and salt, often with other preservatives and flavorings. Pickled onions are usually pickled in malt vinegar and the onions are about 25-26 mm in diameter. Silverskin onions are pickled in white vinegar, and are much smaller. Full sized onions, e.g. Spanish Onions, can be pickled if sliced first.
