San Pedro Atocpan is a small town that produces some 60 percent of the mole eaten in all of Mexico, and Rick is pretty much the perfect tour guide to show us around. We'll see mole in its many mouthwatering forms, including the elegant mole madre at Enrique Olvera's Pujol. In his Mexico City kitchen, Rick leads a lesson in red mole making. In Chicago, he makes a herbacious mole verde with fish that will make you the hero of the kitchen.
