This Mexican seafood cocktail, known traditionally as a cóctel de mariscos, is a vibrant and refreshing dairy-free starter that perfectly balances zingy citrus with savoury seafood. Unlike a vintage British prawn cocktail, this version uses a light tomato and lime base infused with coriander and a hint of spice, rather than a heavy mayonnaise dressing. It is a fantastic choice for a summer dinner party or a light lunch when you want something impressive yet effortless.

Packed with protein from succulent lump crabmeat and tender baby prawns, this dish is as nutritious as it is flavourful.
