If you have a bamboo mat, this easy sushi recipe could easily be turned into an uramaki sushi roll, using your rolling mat to fashion a sushi roll with the crab and veggies in the the center (follow these easy step by step instructions). Or you can skip the rolling, and make a king crab sushi bowl, with a foundation of white rice (seasoned with sushi vinegar), then topped with all your fresh veggies, condiments and miso butter crab.
