12 king prawns, peeled, heads removed & deviened

1 tbsp butter

Juice and zest of 1 lime

Pinch sea salt

Pinch freshly ground black pepper

Melt the butter on your barbecue plate or in a pan. Toss the prawns in a ceramic or plastic bowl with the remaining ingredients, then throw on the plate in the melted butter. Toss quickly, turning regularly until all the prawns have coloured bright orange, then remove and serve immediately.
