WHAT YOU DO
Step 1. Sweat the onion and leek with the thyme and garlic until soft with no colour.
Step 2. Deglaze the pan with Champagne and reduce, add in the fish stock, reduce by half then add in the cream, taste and season. Leave this to cool.
Step 3. Divide the fish between 6 small pots or ramekins, and pour over the cream mixture just to slightly cover the fish mixture.
Step 4. Cut a disc of pastry to cover the top of each pot, then cut out a hole in the centre of each dish. Place the unshelled prawn into the hole.
Step 5. Egg wash the pastry. Bake at 180 for 15 minutes until cooked and golden brown.
