Pearl onions are a type of small, round, white onion that are often pickled and used in cocktails, as well as in various dishes like casseroles and Indian onion relishes. They are harvested when they are 1 inch (25 mm) or less in diameter and are known for their sweet taste.
To peel pearl onions, the root end should be cut off and a shallow crisscross cut should be made on the trimmed edge. The onions should be placed in a saucepan with enough water to cover them and boil for two minutes before draining. Once cooled, the outer skins can be easily removed by gently squeezing the onions with your fingers.
