Squeeze half of the lemon over the shrimp and sprinkle them with a little salt.
Mix together the remaining lemon juice, tomatoes, horseradish, Worcestershire, hot sauce, celery, vodka and pepper in a small pitcher.
When ready to serve, pour the sauce into martini glasses.
Hook the shrimp, around edges. Garnish with lemon wedges, if desired.
TIP: Chill some martini glasses in your freezer the morning of your dinner club party to serve these cocktails.
