Half a teaspoon anchovy essence
Half a lemon, juiced

Still the bestseller on the J Sheekey menu, our fish pie is rightly as famous as some of our customers. A true theatre dish. Some people add lobster, prawns or peas to their pie. We prefer this purer version.

To make the sauce, melt the butter in a heavy-bottomed saucepan over a low heat and gently stir in the flour. Gradually add the wine, stirring well. Slowly add the fish stock (a good-quality cube is fine) until you have a silky smooth sauce. Bring to the boil and simmer gently for 15 minutes. To finish, add the cream and briefly bring to the boil again. Stir in mustard, Worcestershire sauce, anchovy essence and lemon juice. (Add more mustard and Worcestershire sauce if you like it spicy.) Check seasoning.

Gently fold the fish and parsley into the hot sauce, and pour into a large pie dish, leaving a space of about 3cm from the top of the dish. Leave to cool, so the topping will sit on the sauce when piped.

Pre-heat the oven to 190C/gas mark 5. Mix butter and milk into the mashed potato until soft enough to spread over the fish mixture. Season. Pipe or gently fork to cover the fish.

Bake the fish pie for 30 minutes. Sprinkle over the breadcrumbs and cheese, and bake for a further 10 minutes until golden.
