Makes about 8-10

150ml vodka
3tbsp Worcestershire sauce if you wish
The juice of 3 lemons (approximately 90ml)
2-4tsp Tabasco, depending on how spicy you like it
800ml tomato juice
2tbsp freshly grated horseradish
Celery salt
5 leaves of gelatine

In a large bowl, mix all of the ingredients together, except the gelatine, and leave to infuse for about 45 minutes, then strain through a very fine-meshed sieve.

Soak the gelatine leaves in cold water for 3-4 minutes, then squeeze out the excess water.

Bring about 100ml of the liquid to the boil and stir the gelatine leaves in until dissolved; then stir into the rest of the liquid.

Pour into shot glasses or similar and leave for about 45 minutes in the fridge to set.
