I grew up in Maryland. My husband-to-be hails from Louisiana. Though our hometowns were quite different, one thing unites both states: seafood. We both grew up digging into hard-shell crabs on tables spread with butcher paper, learning as young tykes how to extract as much meat as possible from each one. But that’s where the seafood similarity ends. We happened to visit both families on back-to-back weekends this summer, which presented the perfect opportunity for a regional crab smackdown.
