, is a root vegetable belonging to the Yam family. Although I have seen them plenty of times at the wet market, it is still my very first attempt cooking the fresh variety. One interesting thing about this root was how slippery it would become the moment you started peeling off it's skin. It is almost like trying to grab a live eel which is desperately trying to wriggle out of your grasp! The soup is exceptionally flavorful that I do not even have to add any salt or MSG and I am amazed to find that Huai Shan tasted almost similar to the potato in texture. I am so loving this soup! Here are some benefits of the Huai Shan : - Antibiotic - Antioxident - Lowers blood sugar - Prevents osteoporosis - Lowers blood pressure - Improves digestive system I hope you enjoy this as much as I do.
