Ginger Coconut Soup with Wai San and Shrimp Recipe

March 26, 2013

Wai San is a potato-like root vegetable that I discovered at an Oakland Farmers market several years ago. It turned out to be delicious addition to this ginger coconut soup!

I watched the mass of shoppers hover around the table for at least 10 minutes before I mustered up enough courage to elbow my way in and take a look. I was surprised to see a knobby, speckled, skinny root vegetable staring back at me. I had no idea what it was and given all the hustle around me, I doubted I’d get an answer even if I asked.

 

 

I walked away, but it didn’t take long for my curiosity to get the better of me. Finally, on my last lap through the Farmers Market there was a lighter crowd swarming the vendor. I stepped up, analyzed the unfamiliar root, and I caught his eye. I asked what it was. He responded twice with the proper name, and I’m sure my face revealed that not only could I not hear over the people, but that I also couldn’t understand him.

His next response was, “Chinese potato. You cook it like potato in a soup.

Sold. I grabbed up a handful and he nodded in acknowledgement that I only needed a few for soup.

 

 

After a bit of research, I think I finally found the name for this new-to-me vegetable. I say – I think – because it wasn’t easy to come by. I have found a couple of blogs which identify it as Wai San.

It’s long and thin, and almost looks like it has dots. Check.

When it’s peeled, its starch is sticky and a little glue-like. Check.

It boils up like a potato, yet it has a blander flavor. Check.

If you happen to know it by another name, please let me know in the comments. I’d love to learn more about it.

This being my first attempt at cooking with Wai San I didn’t want to get too adventurous. I stuck to the recommendation for soup, and I wasn’t let down.

Cut into small pieces, it takes less time to cook than potato. It has a similar texture, but it’s less starchy. It’s almost like a cross between a carrot and a potato, but with little flavor. That is, until you mix it with the ginger, coconut milk, and shrimp in this soup. Then it becomes all kinds of delicious.

    It is a type of yam, slimy after peeled, isn’t it? True, I too like having yam in soups, various soups; this refreshing version included : ).
