Here is what I do for a bloody mary, even though it is mix based (I don't know anyone that makes a great one from scratch)
Tall glass with ice
Vodka (I use 2/3 Absolut Peppar 1/3 Absolut Citron...extra spice and a little citrus note as well)
Top off with Mr & Mrs T's Bold and Spicy Bloody Mary Mix (About the best I have found...be sure to get the bold and spicy though)
Couple splashes of tabasco (green or red works)
Couple of shakes of black pepper and celery salt)
Stir with celery stalk, garnish as needed (I like a lime wedge, pickled dill beans (although hard to find) and if I am spendy, a couple of cocktail shrimp on a toothpick
If your guests are not up to the hotness, less of the spicy absolut and cut the tabasco...but the bold and spicy mix is way better than the normal
