According to legend (and lots of reliable reporting), the salad was created by Cesare Cardini (whose name is sometimes misspelled as “Caesar Cardini”), an Italian American chef who moved his restaurant to Tijuana from San Diego after the start of Prohibition. The spot became popular both with locals and visiting Americans (who poured over the border regularly to wet their whistles); as such, the restaurant often ran out of ingredients. On one such night, when the restaurant’s usual salad was 86’d, Cardini threw together a combination of romaine lettuce, Parmesan cheese, lemon juice, olive oil, eggs, and Worcestershire sauce. The result was so good, he added it to the menu.
