This is one of my favourite fish dishes and it is so easy to put together. All you have to do is combine the ingredients in a baking dish and bake for about half an hour. You do have to boil down the sauce later, but that will take you only an additional five minutes. I like to serve this dish with Mushroom pullao and Saag aloo. If you cannot get haddock, use any other thick-cut fish, such as cod or halibut.
