A Caesar salad (also spelled Cesar, César, and Cesare), also known as Caesar's salad, is a green salad of romaine lettuce and croutons commonly dressed with lemon juice (or lime juice), olive oil, eggs, Worcestershire sauce, anchovies, garlic, Dijon mustard, Parmesan, and black pepper. The salad was created on July 4, 1924, by Caesar Cardini at Caesar's in Tijuana, Mexico, when the kitchen was overwhelmed and short on ingredients. It was originally prepared tableside, and it is still prepared tableside at the original venue.
