Sato Imo "Country Potatoes"

by Elizabeth Andoh

 

Sato imo (“country potatoes”) Colocasia esculenta are also known as taro potatoes in many markets. They boast a creamy texture and a low Glycemic Index (unlike other potatoes with a high GI that cause peaks and crashes in blood-sugar readings). The tubers are thought to have originated in eastern India and have traveled east to Southeast Asia, China and Japan… and west to Egypt, West Africa and from there to the Americas.

Cultivated for their edible corms (tubers, or “potatoes”) and stalks (these are sold sun-dried as zuiki), the plant contains (toxic) calcium oxalate that must be treated before consumption.

Possibly the earliest known cultivated plant, sato imo remains an important staple in many food cultures throughout the world today. In Japan, there is evidence that the tubers were first consumed by Jōmon-jin, the hunter-gathers who inhabited the archipelago thousands of years ago.

Before they can be eaten, sato imo must be washed and boiled (or otherwise cooked). If the tubers are peeled raw, naturally occurring but irritating oxalic acid can cause hands to itch. The Japanese down-home remedy for this is vinegar; washing itching fingers with acidulated water does bring relief.  Many Japanese cooks, though, prefer to avoid peeling altogether. Instead, they rough-wash the raw tubers imo arai-style to the point they can be cooked with their thin, tasty and nutrient-rich “skins” intact.

IMO ARAI potato-washing is done either by harnessing Nature's energy in the form of a fast-flowing stream (the imo arai kuruma wheel, to the left).

 

 

 

 

 

 

 

 

 

Or, by hand with paddles in a barrel (the community-sponsored, post-harvest festival, below).

Goro goro, goro goro

… the sound of tumbling tubers being rubbed and scrubbed…

 

IDIOM of INTEREST: the phrase imo arai is used to describe people in over-crowded conditions. Peeking inside the barrel, you can understand why the agitated action of potato-washing is a fitting way to portray packed trains at rush hour and swimming pools with standing-room only!

Detox methods include steaming, par-boiling, and/or soaking for at least 8 hours in an alum solution (yaki myōban sui).  Instructions for this are included in this downloadable recipe

My cookbook, WASHOKU:Recipes from the Japanese Home Kitchen (Ten Speed Press, 2005) provides a solid introduction to the principles and practice of harmony and balance (washoku) in the kitchen and at table. This workshop page enables me to guide you further.  ENJOY!
