This week, we taste the sweeter side of Mexican cuisine with chef Fany Gerson. Traveling from Mexico City to Veracruz to Oaxaca, we explore regional confections like chili-flavored paletas and guava and cheese doughnuts. Plus, we take a seat at the Noir Bar with writer and television host Eddie Muller, who infuses classic cocktails with a cinematic twist; Martha Barnette and Grant Barrett of “A Way With Words” unpack the history hidden in your spice cabinet; and we prepare a very crispy Korean Fried Chicken.
