David meets with chef Marilu Madueño of La Huaca Pucllana, one of the best restaurants in Lima. After learning the significance of how Peruvian ingredients shaped the world's food, David travels across the country to source these foundational ingredients. After heading into the Andes to check out Incan ruins, he harvests quinoa, corn, and potatoes, slaughters a duck, and, in a final test of his fortitude, becomes a Mata Cuy.
