If any one man is the foremost authority on Gumbo, it is Brett Anderson. Through two decades as a food writer in New Orleans, he has sampled more gumbos than most people will in a lifetime. And he's shared his knowledge with the masses: in 2004, he wrote: "Gumbo, Louisiana's Bowl of Wonder," a definitive guide to the state's signature dish. Some 15 years later, he wrote the coda to that story for the New York Times: "Gumbo, the Classic Louisiana Dish, is Dead. Long Live Gumbo," chronicling the new influences and ways chefs were putting their own touches on the dish. Brett joined the Gumbo Show to discuss his experiences with gumbo, what he's seen, where he loves to get a bowl and why gumbo is so interesting.
