As you probably know, whole crabs in general are difficult to find in your everyday market. Live crabs are, of course, even harder to find. But I've struck gold, and it's even better than regular old live crabs. Today, we're making sushi from live soft shell crabs. Soft shell crabs are an absolute delicacy. You can eat virtually the entire crab, and it's one of the juiciest things you'll ever experience. They're typically Japanese blue crabs, oftentimes from Maryland. And when you wrap this all into a sushi roll, you get something truly special.
