National Caesar Salad Day is observed in the United States on July 4th each year, coinciding with Independence Day. This day celebrates the Caesar salad, which was created by Italian chef Caesar Cardini in Tijuana, Mexico, in 1923. According to Cardini's daughter, the salad was invented during a busy Fourth of July weekend when the kitchen's supplies were low. The original recipe included whole lettuce leaves, coddled eggs, olive oil, lime juice, and Worcestershire sauce, although variations have emerged over time, often incorporating ingredients like anchovies, croutons, and Parmesan cheese. To celebrate, people are encouraged to enjoy Caesar salad at their favorite restaurants or prepare it at home, experimenting with both classic and creative recipes. The holiday is promoted on social media with the hashtag #NationalCaesarSaladDay, as it often gets overshadowed by the Independence Day festivities.
