Step 1 : Introduction to the question "Caesar salad is celebrating its 100th anniversary. It was first served at a restaurant in which country?"
The Caesar salad, a staple in many restaurants worldwide, is celebrating its 100th anniversary. This iconic dish was first served in 1924 at Caesar's Restaurant in Tijuana, Mexico. Created by Italian-American restaurateur Caesar Cardini, the salad became an instant hit. The original recipe included “romaine, garlic, croutons, and Parmesan cheese, boiled eggs, olive oil and Worcestershire sauce.” Supposedly Cardini’s brother, Alex, came to Tijuana in 1926 and added anchovies to the salad. Cardini's creation quickly gained popularity, eventually becoming a beloved classic in international cuisine.
