The chef Paul Prudhomme's recipe for blackened redfish once became a national craze. Mr. Prudhomme dipped redfish fillets in butter, dusted them with ground cayenne and a mix of dried herbs, and seared them in a red-hot iron skillet until a black crust formed. The dish became so popular that the redfish population in the Gulf of Mexico came under threat. You could use fluke, flounder or porgy, instead. Any firm white-fleshed fish will do.
