Baked fish might inspire a boring weeknight feeling, but this slowly baked, tender cod served on top of potatoes flavored with ham fat is anything but—it’s easy enough for a weeknight but tasty enough to share. If you’re having friends over or just want to go the extra mile, serve this with Mother-Sauce Mayo on the side. It’s hard to believe that pork-flavored potatoes could get even better, but wait until you try pork-flavored potatoes with handmade mayonnaise.
