Ingredients

12 cups watermelon chunks (from one 4-pound watermelon, rind removed), plus pieces, for serving

1 teaspoon sugar, or to taste

Ice, for serving

1 1/2 cups tomato juice

13 dashes hot sauce, such as Tabasco, or to taste

1 1/2 teaspoons Worcestershire sauce

1 1/4 teaspoons coarse salt

1/2 teaspoon celery seeds, ground with a mortar and pestle, or celery salt

Freshly ground pepper

1 to 1 1/4 cups vodka

Celery stalks, for serving

Preparation

Working in batches, puree watermelon (with seeds) and sugar in blender. Strain into a bowl through a fine sieve, pressing with a rubber spatula; discard solids. (You will have 5 1/2 cups juice.)

For children’s drinks: Divide 2 1/2 cups juice among 4 ice-filled glasses.

For adults’ drinks: Stir remaining 3 cups watermelon juice with tomato juice, hot sauce, Worcestershire sauce, salt, and celery seeds in a bowl set in a larger bowl of ice. Season with pepper. Stir in vodka and divide among 4 ice-filled glasses.

Garnish adult drinks with a piece of watermelon and a celery stalk.
