Shellfish is often overlooked in the perpetual hunt for healthy quick dishes. I love to look east for inspiration, as I have done here with the motoyaki recipe, a popular Japanese way of cooking oysters with mayonnaise on top, finished under the grill. A razor clam has a gentle texture, somewhere between a clam and a squid and they are extremely popular in Asia and in most of Europe. I don’t know why they aren’t popular here. They make an elegant and very impressive dish.
