Sho Kamio, the San Francisco Bay Area-based chef who shared this recipe with us, buys live shellfish in the shell, shucks it, then grills it in the half shell until bubbling and cooked through over medium-high heat for 3 to 8 minutes depending on the shellfish, covering the grill for a few minutes along the way. This adaptation uses the stovetop. If you don’t want to shuck your own shellfish, have your seafood monger do it for you.
