Pour the mix into a pitcher or open container so it's easier to add other ingredients and stir the mixture.
Add the horseradish, pepper, salt, mustard, old bay seasoning and Worcestershire sauce and hot sauce.
Squeeze the juice of half the lemon, and then stir vigorously.
To serve, rim the glass with Old Bay seasoning, add 2 oz of vodka per cocktail and fill with ice.
Pour the ready Bloody Mary mix and garnish with celery, olives, lemon slices and cornichon pickles. (Or any other salty goodness you like.)
