A caesar (also known as a bloody caesar) is a cocktail created and consumed primarily in canada. it typically contains vodka, a caesar mix (a blend of tomato juice and clam broth), hot sauce, and worcestershire sauce, and is served with ice in a large, celery salt-rimmed glass, typically garnished with a stalk of celery and wedge of lime. what distinguishes it from a bloody mary is the inclusion of clam broth. the cocktail may also be contrasted with the michelada, which has similar flavouring ingredients but uses beer instead of vodka.
