The crab fluff is virtually unheard of outside of Maryland and somewhat controversial within it (some locals love it, others don't see the appeal). It's a crab cake that's been battered and given a dunk in the deep fryer, resulting in a crisp golden sphere with gooey crab inside. The "hard fry" or "fried hard crab" carries things a step further. Cooks take a whole blue crab (sometimes steamed, sometimes uncooked), stuff a crab cake into the cleaned body cavity, then dredge the whole thing in a thick seasoned batter and deep fry it. Greasy, spicy, crunchy, and decidedly space alien in appearance, it's definitely a form of novelty food. But you won't find anything like it in Charleston or Boston. Something of an old-school indulgence, hard-fried crabs are getting increasingly rare, but they're still battering up both crab fluffs and hard fries at Bo Brooks Restaurant and out at Ocean Pride in Lutherville.
