Red Swamp Crawfish
A tier
Red swamp crawfish is the market name shoppers and menus use for Procambarus clarkii sold live or as frozen tails. Expect bright red shells after boiling, plump tail meat, and the classic Cajun boil aroma when seasoned hard with cayenne, garlic, and lemon. Compared with cooler-water European species, red swamp meat is slightly softer and more forgiving in stews. Purge if muddy, boil hard with spice, and peel at the table—or buy pre-peeled tails for weeknight étouffée. Size grades (select versus field run) matter more for presentation than for flavour. Pair with rice, corn, sausage, and cold beer rather than delicate sauces that hide the spice.
