If you could define the singular challenge facing Yucatecan chefs, it's about honoring the past while pushing forward. Perhaps no one is more emblematic of the effort than Pedro Evia, co-owner of Ku'uk, a molecular fine dining palace housed in a restored Merida mansion. Rick and Pedro start their day talking tradition over tacos at Wayan'e, a busy family-run taco stand in Merida. Then, Pedro invites Rick to his home, where Pedro and his mother make traditional sopa de lentejas. At Ku'uk, Pedro shows us his ultra-modern take on the same dish. Back in Chicago, Rick makes recado negro to complement cured duck. At home, he makes tacos with eggs and burnt habanero salsa, avocado and red onion - the perfect chef's late-night snack.
