What Is Satoimo (Taro)
Satoimo is a mild-flavored starchy root vegetable widely enjoyed in Japanese cuisine. Compared to other varieties of taro, satoimo is smaller in size with a round body, hairy brown skin, and tapered ends. It has firm and creamy white flesh and a somewhat slimy texture like okra that can irritate the skin. Satoimo grows throughout the year and is available year-round.
It’s high in fiber and potassium and low in calories than potatoes, making it a healthier alternative without compromising the starchy texture. The Japanese people use satoimo in miso soup, kenchinjiru, and nimono.
The sliminess is similar to nagaimo (長芋) and yamaimo (山芋), a type of mountain yam, but its culinary uses differ.
What Does It Taste Like
It has a mild creaminess with a hint of nuttiness.

How To Use
The thick hairy skin can be hard to peel. Before peeling, rinse it well underwater and remove the dirt and hairs as much as possible. You can use a vegetable scrub or Japanese tawashi (束子, bristled scrub). If you have sensitive skin, you may want to wear kitchen gloves as protection from calcium oxalate that can irritate the skin. Once cooked, the irritating substance will go away.
Using a kitchen knife, cut off both ends first and peel from one end to the other with a knife or peeler. It gets slimy when peeling, so take caution when handling it.
To eliminate the sliminess, use salt to rub the surface and rinse under cold water. Drain and cut into half or bite-size pieces and add it to cooking.
