Curing Sweet Potatoes: Why Sun-Drying Beats Kiln Drying

Curing (suberization) thickens skin and converts starch to sugar. Ideal: 80°F for 7 days, then 60°F for 7 weeks. Home gardeners can use a sunny cardboard box for a week. Controlled curing yields better flavor than simple sun-drying. Seek hand-cured roots at farmers markets.
