New Orleanians have always loved to cook and to share what they've made with others. So it makes sense that as soon as there was television, there was a Crescent City chef on the screen spreading the good news of New Orleans food. The first was an African American cooking star named  Lena Richard, who made her TV debut on WDSU-TV in 1949. Fast forward to today, and it’s tough to tune in to any cooking show and not see a familiar face. This week, three local chefs walk us through the fun and the frenzy of their television encounters.
