Measure the tomato juice, vodka and lemon zest and juice into a large non- metallic jug. Add the Worcestershire sauce, Tabasco and a pinch of salt. Stir well and add more Worcestershire sauce or Tabasco to taste depending on how spicy you like it.
Cover and chill for at least 1 hour or until ready to serve.
Mix the celery salt, pepper and sea salt together on a small plate. Dip the rims of 16 shot glasses into a little lemon juice or water to wet the rim only, then dip into the salt and pepper mix to coat the edges. Set aside.
When ready to serve, thread a lemon slice, caper berry, or olive, and a prawn on to 16 cocktail sticks. Carefully pour the Bloody Mary into the shot glasses, and place a filled cocktail stick on top of each glass.
