Featured on Fish the Dish, this vibrant seafood dish balances heat, citrus, and sweetness for a quick yet flavour-packed meal that’s perfect for grilling season or easy entertaining.

The Inspiration

This dish is inspired by the bold, spice-forward traditions of Cajun and Creole cooking, where seafood is often seasoned heavily and cooked quickly over high heat to preserve its natural sweetness. The Cajun spice blend brings warmth, smokiness, and heat, while lime and honey introduce a bright, balancing contrast.

On Fish the Dish, host Spencer Watts often explores how global spice traditions can be adapted into simple, high-impact seafood dishes. This recipe reflects that approach by pairing grilled prawns with a silky beurre-blanc-style butter sauce that is elevated with citrus and honey.
