A Caesar salad has romaine lettuce (lechuga romana) and croutons (=small pieces of bread fried in butter an oil) dressed (aderezada) with parmesan cheese, lemon juice, olive oil, egg, Worcestershire sauce (salsa inglesa), and black pepper. Worcestershire sauce contains anchovies (anchoas) and garlic (ajo).
Many people believe the Caesar Salad owes (debe) its name to the Roman emperor Julius Caesar. The name Caesar, however, comes from the original creator of the salad: Caesar Cardini. Cardini was an Italian-born Mexican who lived in San Diego and had a restaurant in Tijuana.
According to Caesar's daughter Rosa, on July 4th 1924 the salad was created on a busy weekend at Caesar's Restaurant. It is said that Caesar was short of (se quedó sin) supplies (provisiones) and didn't want to disappoint the customers so he created this salad with what was on hand (a mano). The salad soon became a hit and people came to the restaurant just to get the salad. In particular, the Caesar salad became a favourite of Hollywood actors. Many restaurants serve a Caesar salad with grilled (a la parrilla) chicken, steak, salmon or shrimp (camarones).
