To prepare the prawns

Remove the shells and devein the prawns, keeping the heads on. Keep the shells to use in the stock.

Put the prawns, garlic, chilli and olive oil into a bowl, cover and marinate in the refrigerator until needed.

To make the stock

Heat the olive oil in the casserole on a low to medium heat, add the prawn shells, onion and ginger then fry gently for 5 minutes, stirring frequently.

Add the coconut milk, bring to the boil and reduce by a third, season with half a teaspoon of soy sauce, half a teaspoon of fish sauce and salt and black pepper.

Strain the stock into a container and discard the shells and vegetables.

Allow to chill and refrigerate until needed.

To make the salsa

In a bowl mix the mango, red onion, basil, chilli, lime juice and zest, 2 tablespoons of olive oil and season with salt and black pepper. Cover and refrigerate until needed.

To prepare the crushed avocado

Cut the avocado in half, remove the stone and then the flesh. Roughly chop the flesh, put in a bowl along with the soured cream, coriander and juice and zest of half a lime. Season with salt and pepper.

Place a layer of clingfilm directly onto the avocado mixture, this will prevent the avocado from turning brown, and refrigerate until needed.

To cook and assemble

Remove all items from the fridge, gently heat the stock in a small saucepan.

Heat the grill on a medium heat setting; meanwhile brush the sourdough slices with a little olive oil. Test the temperature of the pan – and when hot enough place the bread onto the grill and toast on both sides. Remove and spread one side of each slice with crushed avocado and place on a stoneware serving platter until needed.

Test the temperature of the grill again with a little water and, if hot enough, add the prawns and cook for 3 minutes on each side. For the final 30 seconds, turn down the heat and pour in the remaining marinade of chilli, garlic and olive oil.

Remove the pan from the heat. Carefully place three prawns on top of each slice of avocado toast and spoon over the pan juices.

Spoon the mango salsa around the toast, then drizzle with stock.

Serve with a hot water and lemon finger bowl.
