Just in time for Mardi Gras, we’re inviting chefs — professionals and amateurs — to help us fight fracking by competing in a New Orleans Gumbo Cookoff. The event, at Jimmy Carbone’s East Village restaurant, Jimmy’s No. 43, on Sunday February 19, 1-3 p.m., will benefit Chefs for the Marcellus. Participants include The Green Table, NYC Hot Sauce, Goat Town, and others. Sign up, or learn more!
