For the Bloody Mary base: In a large pitcher, stir to combine the tomato juice, clam and tomato juice, lemon juice, horseradish, Worcestershire sauce and hot sauce.
For the Bloody Mary bar: Set up a large table with glasses, ice in a bucket with tongs, vodka and the remaining Bloody Mary bar ingredients and garnishes. Have stirring sticks, straws and toothpicks available to skewer garnishes.
