This isn't your typical fried fish and chips style dish. The fish is baked and the potatoes are scalloped in this dish. It is made with a white sauce that contains crème fraiche and is infused with some fresh thyme and garlic. The very thinly sliced potato topping ends up baking up to be a lovely golden brown and the fish is flaky and tender. This is fairly simple to prepare and a great lighter variation on the standard fish and chips. This comes from a book called "Sunday Casseroles" by Betty Rosbottom, though I have made some very minor changes.
