A Summer's Night Prawns Cocktail

This summer prawn cocktail is a sophisticated, high-protein twist on a classic starter. By charring the tomatoes under the grill before blending them with smoky chipotle and lime, the sauce gains a deep, savoury complexity that far surpasses traditional bottled versions. The combination of chilled, succulent prawns with creamy avocado and crunchy cucumber creates a refreshing contrast of textures that is perfect for warm-weather dining.

Ideal as an elegant first course for a dinner party or a light weekend lunch, this dish is as nutritious as it is flavourful. The use of fresh coriander and a hint of jalapeño adds a vibrant Mexican influence to the plate. Serve it in tall sundae glasses with salty crackers and plenty of lime wedges for a beautiful presentation that your guests will love.

Ingredients for A Summer's Night Prawns Cocktail

  • 3 Roma tomatoes, halved lengthwise, plus 40g seeded and diced ripe tomato

  • 3.8L plus 120ml water

  • 60ml plus 2 tablespoons freshly squeezed lime juice

  • Kosher salt

  • 675g medium-size prawns, tails removed, peeled, and deveined

  • 2 tablespoons sauce from chipotle chillies in adobo sauce

  • 1 1/2 tablespoons honey

  • 1 small clove garlic, minced

  • 1 teaspoon Worcestershire sauce

  • Pinch of freshly ground black pepper

  • 1 avocado, halved, pitted, peeled, and cubed

  • 80g cubed unpeeled English cucumber

  • 40g chopped yellow onion

  • 1/4 cup loosely packed chopped fresh coriander

  • 1 tablespoon minced jalapeño chilli (optional)

  • Saltine crackers, for serving

  • Lime wedges, for serving

Position a rack on the top level of the oven, about 4 inches from the grill. Turn on the grill. Line a rimmed baking sheet with aluminum foil. Place the tomato halves on it, cut side down. Grill for 10 to 12 minutes, or until the tomatoes are softened and slightly charred. Allow to cool to room temperature.

Combine 3.8L of the water, 60ml the lime juice, and 2 tablespoons salt in a large saucepan and bring to a boil over high heat. Add the prawns and cook for about 3 minutes, until they are fully cooked. They should be bright pink-orange, curled, and firm but not hard. Immediately drain the prawns into a colander and hold under running cold water for about 1 minute. Drain well, transfer to a bowl, cover, and refrigerate until cold.

To make the cocktail sauce, combine the roasted tomatoes, the remaining 120ml water, the remaining 2 tablespoons lime juice, the adobo sauce, the honey, the garlic, the Worcestershire sauce, and the pepper in a blender and puree on high speed until smooth. Season to taste with salt.

Pour the sauce into a large ceramic or glass bowl. Add the prawns, avocado, cucumber, onion, diced tomato, coriander, and jalapeño. Stir gently to mix.

Serve in tall glasses or sundae glasses with long spoons and accompany with the crackers. Pass the lime wedges at the table.
