Recipe : Fresh huái shān/wai san (淮山) soup

I have always wondered what are those dull looking roots sold at the supermarket. So, yesterday when I was at the wet market with this kind vegetable seller, he got me into discovering a new vegetable. He has this box of root vegetable in a box with sawdust (to absorb moisture, I think).

He told me it is fresh wai san and makes a very healthy and good soup. I have used dried wai san in my Chinese herbal soups but never know that fresh ones taste great. The dried ones are tasteless and I usually discard without eating.

The ugly looking piece of root. It is very slimey and hard to hold when wet. I skinned it, slice it into pieces and cook it as a soup with some spareribs and red dates. I learnt that wai san is part of the yam family. You can read more about it from Wiki. Lesson learnt : Skin and cut the wai san first before washing. Otherwise, it is like a piece of eel.

The wai san gives a nice, wholesome taste to the soup. It is good too, without being flour-y (unlike yam) or have that earthy smell like white radish. So, don’t underestimate the goodness of an ugly vegetable! 😛

Wai San is going to be my regular purchase from now on.

    Add some tungsum & kei chi as it’s good for lung and eyes. Another vege which makes very good soup is fan kok. Very sweet, just put a small piece in your soup. This 2 types of vege has been in the market for quite a while.

    I read somewhere that Wai san is good for those suffering for gastric trouble. Never cook with fresh one before. Would like to try.. I always put dried wai san, tong sum, kei chee, yuk chuk , pak kei and some red dates in my soup.

    sooii2 – Wrong timing cos I was upgrading the blog and it was temporary down.

    molly – I must try this next time. In fact, I have some of the herbs in my fridge too. Just lost on what to do with them. Now I know.

    ling – How does fankok looks like? I will ask the vege seller next time. Tks.

    Chris – It is much nicer than white radish and have similar texture like lotus root.
