Fillets of Cod with Creamy Prawn and Dill Sauce

Cod is an often underrated fish, not associated with more sophisticated dishes. Cooked carefully, however, its large flakes should be moist and smooth with a delicate flavour. These fillets are poached lightly in a white wine and prawn stock, which then becomes part of the creamy prawn sauce, making it a luxurious dish. Serve with new potatoes and a green vegetable.
