The Caesar (or Bloody Caesar) is Canada’s national cocktail, consumed at a rate of over 350 million per year. It was invented in 1969 by restaurant manager Walter Chell at the Calgary Inn to celebrate the opening of a new Italian restaurant. Inspired by the flavors of Spaghetti alle Veltovole (spaghetti with clams), Chell combined vodka, tomato juice, clam broth, Worcestershire sauce, and spices. The key difference between a Caesar and a Bloody Mary is the 'Clamato' juice—a blend of tomato and clam juices. The drink is traditionally served in a glass rimmed with celery salt and garnished with a celery stalk and a lime wedge. It has since evolved into a vehicle for 'extreme' garnishes, with some bars topping the drink with everything from sliders to fried chicken.
