The Sacred Valley of the Incas or the Urubamba Valley is a valley in the Andes of Peru, close to the Inca capital of Cusco and the ancient city of Machu Picchu. It is located in the present-day Peruvian region of Cusco. In colonial documents it is referred to as the “Valley of Yucay.”
The Giant White Corn of Cusco has the largest kernel in the world, and is produced only in specific districts of the provinces of the Sacred Valley of the Incas in Cusco.
It resists drastic climate changes and seems to be particularly resistant to plagues. Farmers dry the corn according to an ancient custom that requires a combination of frost at night and bright sunshine for 45 days, after which the kernels are removed.
