Dried Chinese yam
The rhizome of Chinese yam, sold as chalk-white flat dried sticks and slices, or fresh for slicing at home. Mild and starchy, it thickens the broth slightly and adds a soft, comforting bite; the dried slices need only a brief soak and rinse.

Cautions: read first
- Not to be eaten in quantity if damp is heavy and you feel full in the middle, or if your stools are dry and hard
- When choosing, avoid sulphur-fumigated stock, the sort that looks too white and smells sharp
Preparation
A short soak and rinse is enough for the dried slices. Fresh 淮山 is peeled and cut into pieces, and handling it can make your skin itch, so wear gloves if you like.
