Campechana Extra (Mexican Seafood Cocktail)

This vibrant Mexican seafood cocktail, known as Campechana Extra, is a sophisticated, high-protein dish that celebrates the fresh flavours of the coast. Combining succulent prawns and jumbo lump crabmeat with a tangy salsa base, it offers a beautiful balance of textures. The addition of charred Anaheim or poblano chillies provides a subtle, smoky depth that elevates the dish beyond a standard prawn cocktail, while the creamy avocado adds a cooling richness to every spoonful.

Perfect as an elegant starter for a dinner party or a light, refreshing lunch on a warm afternoon, this versatile seafood dish is as nutritious as it is flavourful. The salsa base can be prepared a day in advance to allow the flavours to meld, making it an excellent choice for stress-free entertaining. Serve it chilled in a tall glass with crunchy tortilla crisps for a truly authentic experience.

Ingredients for Campechana Extra (Mexican Seafood Cocktail)

  • 2 medium New Mexico (also called Anaheim), poblano, or Hatch chillies (about 170g )

  • 230g medium prawns (preferably wild), peeled, deveined, tails removed

  • Kosher salt

  • 1 small tomato, seeded, finely chopped (about 110g )

  • 1–2 jalapeños, stems, ribs, and seeds removed, finely chopped

  • 120ml tomato–clam cocktail, such as Clamato juice

  • 60ml plus 2 tablespoons ketchup

  • 3 tablespoons chopped pitted green olives

  • 2 tablespoons chopped coriander

  • 2 tablespoons finely chopped white onion

  • 1 1/2 teaspoons finely chopped oregano

  • 1/2 teaspoons finely chopped garlic

  • 45ml fresh lime juice

  • 45ml olive oil

  • 230g crabmeat (preferably jumbo lump), picked over

  • 1 avocado, pitted, cubed

  • 1 fresh bay leaf (optional)

  • Tortilla crisps (for serving)

Prepare a grill for medium-high heat or preheat grill. If grilling, place chillies on a rimmed baking sheet. Grill, grill, or roast chillies directly over flame on stovetop, turning occasionally, until very tender and blackened all over, 10–12 minutes. Poblanos might take a little longer, so test doneness with a paring knife.

Transfer chillies to a large bowl. Cover with plastic wrap and let steam 15 minutes. Peel chillies. Halve lengthwise, discard seeds, and chop into 1/4" pieces.

Meanwhile, bring a medium pot of generously salted water to a boil. Cook prawns until just opaque and pink, 2–3 minutes. Using a slotted spoon, transfer to an ice bath and let sit until cool, about 3 minutes. Drain and pat dry.

Mix chillies, tomato, jalapeños, Clamato juice, ketchup, olives, coriander, onion, oregano, garlic, lime juice, oil, and 1/4 teaspoons salt in a large bowl. Carefully fold in prawns, crab, and avocado.

Transfer to a serving bowl or tall sundae glass and top with bay leaf, if using. Serve with tortilla crisps alongside.

Salsa base (without seafood and avocado) can be made 1 day ahead. Transfer to a resealable container and chill.
