Juice 3 to 4 medium lemons until you have ½ cup juice.
Place juice in a blender and add half of bottle or can tomato juice, ¾ cup Worcestershire sauce, ½ cup prepared horseradish, 2 tsp. hot sauce, 1 tsp celery seeds and ¼ kosher salt: blend on high until smooth; about 1 minute.
Pour into an 8 - t0 10 cup piitcher and stir in the remaining tomato juice.
Cover and refrigerate for at least 1 hour or ideally overnight.
Meanwhile, refrigerate 2 cups vodka.
Remove from the refrigerator and taste the bloody Mary mix; season with more kosher salt and more hot sauce, as needed.
To serve individual Bloody Marys: Fill a Collins glass, or mason jar, halfway with ice; pour 2 ounces vodka over the ice: top with about 6 ounces of the Bloody Mary mix and stir until just combined; garnish with a celery stalk, pimento-stuffed olives and a lemon wedge speared with a toothpick.
For a pitcher drink: Add all of the vodka to the pitcher and stir to combine; pour into ice-filled glasses, or mason jars, stirring the drink before each pour (the tomato mixture and vodka may separate as they sit); garnish each drink with a celery stalk, pimento-stuffed olives and a lemon wedge speared with a toothpick.
