The primary ingredient found in a traditional Caesar salad is romaine lettuce. This crispy lettuce provides the foundational leafy base for the salad. A classic Caesar salad typically includes romaine, croutons, Parmesan cheese, and a creamy dressing made from ingredients like garlic, anchovies, egg yolks, lemon juice, and Worcestershire sauce. The combination of flavors and textures, with the crunch of the lettuce and croutons and the richness of the dressing, creates a distinctive and beloved culinary experience. Variations of the Caesar salad may include additional toppings, but romaine remains central to the traditional recipe.
