Combine lime juice, jalapeño, horseradish, prawn pickling liquid, and Worcestershire sauce in a cocktail shaker and muddle until the jalapeño is pulverized. Add ice to fill halfway, then add tomato juice and vodka and season with salt and pepper. Shake vigorously until combined, about 20 seconds.
Strain into a highball glass filled with ice. Garnish with pickled prawns and celery.
