Caesar salad has something to celebrate: It’s turning 100.

Italian immigrant Caesar Cardini is said to have invented the dish on July 4, 1924, at his restaurant, Caesar's Place, in Tijuana, Mexico. It was a steamy night, and Cardini was struggling to feed an influx of Californians who had crossed the border to escape Prohibition.

In the middle of the dining room, Cardini tossed whole Romaine leaves with ingredients he had on hand, including garlic-flavoured oil, Worcestershire sauce, lemons, eggs and Parmesan cheese. A star was born.

Tijuana plans to commemorate the anniversary this month with a three-day food festival, and the unveiling of a statue of Cardini. Caesar’s - an elegant restaurant Cardini opened in Tijuana a few years after the salad was born - says it still makes as many as 300 Caesar salads each day.

Unlike some other menu items from the early 20th century - think creamed liver loaf or aspic - Caesar salad remains a perennial favourite. Around 35% of US restaurants have Caesar salad on their menus, according to Technomic, a restaurant consulting firm. And nearly 43 million bottles of Caesar salad dressing - or $150 million worth -- have been sold in the US over the past year, according to Nielsen IQ.
