The sauce is often a mix of ketchup, mayonnaise, and Worcestershire sauce, giving it a distinctive flavor. It is usually garnished with lettuce and sometimes served in a glass or bowl for an elegant presentation. This dish became popular in the mid-20th century, especially in the United Kingdom, and is often associated with formal dining and celebrations. Prawn cocktail is enjoyed for its refreshing taste and is a staple on many restaurant menus and at social gatherings.
