Otherwise, sustainable, wild-caught shrimp (these from the waters of Port Royal, right near Beaufort, SC) are easy to distinguish from icky, farm-raised shrimp: wild shrimp have pinkish-red legs.
(Thank you, Friendly Safeway Fishmonger Man, for sharing that helpful bit of information with me last year!)
Found myself in Frogmore, SC with a one-item shopping list: SHRIMP.
Best to get it from the source, so we headed to the marsh-front mainstay, Gay Fish Co.
This place is perfect.
(Some people add onion.)
Just don't inhale too deeply cause it's a marsh, and marshes always smell like a raccoon's been dragging dead fiddler crabs up and down the pluff mud.
(Which they have been, actually.)
Someone's been busy arranging detritus out back.
