A Bloody Mary is a cocktail containing vodka, tomato juice, and other spices and flavorings including Worcestershire sauce, hot sauces, garlic, herbs, horseradish, celery, olives, salt, black pepper, lemon juice, lime juice and celery salt. Its origins aren’t exactly clear, but the likely backstory points to the mid-1930s and Fernand “Pete” Petiot, a bartender at King Cole Bar at the St. Regis hotel in New York City.
