Add 625ml milk, bring to a boil over a medium heat, then lower the heat and simmer for 5 minutes or until the fish is just cooked. Strain through a colander and reserve the milk. Transfer the mixture to a large plate, coarsely flake the fish, discard the bay leaf and set aside.

Add the fish mixture and stir through gently. Spoon into a 2-litre ovenproof dish.
