Louisiana produces roughly 90% of the crawfish eaten in the United States, most of it farmed in flooded rice fields during the rotation between rice crops.
Whole crawfish are boiled in huge outdoor pots with corn, potatoes, and sausage in a fiercely spiced, cayenne-heavy broth, then dumped straight onto newspaper-covered tables. Roadside stands and gas-station kitchens sell them by the pound in the spring boil season.
