iso Classic Baked Cod Recipe
I don't know if this a classic New England recipe but it sure sounds a lot like your mum's. Lay your cod in a buttered baking dish. Drizzle some cream over it (about one quarter cup). Then top with bread crumbs (I use fresh or frozen home-made ones), dot with butter and bake covered at 350 until the fish is done - about one half hour. I like to sprinkle some dill weed on the fish before drizzling on the cream for extra flavor.
