  • 2 lobster sliced in half lengthways
  • 450 g king prawns 
  • 300 g crayfish 
  • 150 g unsalted butter softened
  • 1 tsp Maldon salt
  • freshly cracked black pepper
  • 10 g parsley finely chopped 
  • 10 g coriander finely chopped 
  • 2 lemons halved
  • 100 g mayonnaise 
  • 1 tbsp siracha 


  1. Begin by mixing together the herb butter for your seafood. In a small bowl mix together the softened butter with Maldon salt, cracked black pepper, the chopped parsley and coriander. Set aside. 

  2. The perfect way to cook your seafood is on a hot BBQ, however if you don’t have one then a griddle pan will work too. Make sure it has reached a medium to high temperate, and start by grilling your lobster halves. 

  3. Cook flesh side down on the griddle until the meat has turned pink and has some lovely charring on it. The shells will turn orangey pink too, and this is when you know your lobster are cooked.

  4. Repeat with the king prawns and crayfish, although these will take less time to cook.

  5. While your seafood is cooking, it is also nice to griddle some lemon to serve alongside. Simply add your lemon halves cut side down onto the grill and allow them to cook and char for 3 minutes.

  6. Once your seafood is all cooked, pile onto a large serving platter and, using a pastry brush, brush all across the flesh with your delicious herb butter – letting it melt in. Place your griddled lemon onto the serving platter too. 

  7. In a small bowl mix together the mayonnaise and siracha. Serve this alongside the platter of BBQ seafood and allow everyone to tuck in!
