These soba noodles are made with buckwheat flour (soba-ko), wheat flour (komugi-ko), and the special addition of yamaimo, a Japanese mountain yam. Yamaimo has a mild nutty flavor with a special slimy-slippery texture that enhances the soba noodles. Yamaimo soba is a specialty product that needs to be experienced firsthand as its texture and flavor are hard to describe.
Uses: Boil noodles until texture is as desired. Rinse in cold water and strain.
Fresh yamaimo is a popular topping for soba noodles.
