The northern answer to the Bloody Mary. It started in Calgary about 50 years ago.
Clam broth /juice is the secret ingredient

This Ultimate Caesar Cocktail is a total Canadian classic. It’s Clamato juice based with a hit of vodka and the whole thing gets flavour and spice from ingredients like horseradish, Worcestershire sauce and hot sauce.
