 Maryland crabs are prepared by seasoning generously with Chesapeake Bay crab seasoning such as Old Bay and then steaming over, not in, vinegared water (often, beer is added to the steaming water).The Lowcountry boil, Tidewater boil, and Frogmore Stew are variations on the same theme in North and South Carolina.Here, recipes may go in either a Louisiana or Maryland direction.
