It is a season for Satsuma-Imo. You can find all kinds of Yam and Sweet Potato in the market. Japanese Yam, Garnet Yam, White Sweet Potato, Purple Sweet Lord and such. Actually, Yam and Sweet Potato belong to different family. The listed here are actually all sweet potato. Confusing! Nonetheless Sweet Potato, Satsuma-Imo and such, is not only sweet and tasty but also is rich in vitamin C and dietary fiber. How should I use it? Will see.
