Taro Satoimo Preparation Japanese
Japan — satoimo cultivation since Yayoi period; autumn cultural touchstone in Japanese food
Satoimo (里芋, taro, Colocasia esculenta) occupies a central position in Japanese autumn cooking unlike any other culture's use of taro. The small, round Japanese variety (as opposed to the large Hawaiian poi taro) is distinctive for its stickiness (neba-neba) from galactan mucilage, which is a cultural flavor characteristic rather than a defect. Used in nimono (simmered with dashi-soy-mirin), miso soup, and kenchinjiru, satoimo must be parboiled first to reduce the calcium oxalate that causes irritation and to remove some of the sliminess. The combination of tender earthiness with the sticky texture is considered a defining autumn flavor.
