Nutrition
This mild-tasting tuber is mainly composed of starch but also contains a small amount of protein. The characteristic sliminess when peeled is said to be the result of polysaccharides bonding to the protein content. Taro is a common ingredient in boiled and deep-fried dishes.
Storage
Japanese taro (satoimo) do not do well in dry environments, so it is best to store covered in dirt. Also, try to select taro that are symmetric in shape, do not have bumps or cracks and which have moist peels. Refrigerators are too cold and are thus not suitable for storage. Try to store at temperatures around 15℃ (59℉).
Cooking Tips
Japanese taro are recommended for simmered and deep-fried dishes.
Cooking Basics
When satoimo are boiled or simmered, they becomes slimy and broth becomes murky and thick, so sprinkle on salt and rub all over before cooking satoimo. The recommended amount of salt is about 2 Tbsp per 5 to 6 satoimo. Place these into a pot, add plenty of water, and cook over high heat until bubbles begin to form. Rinse quickly in water to remove the sliminess. You can use this method to prepare dashi-flavored simmered dishes having clear, light broth.
Once peeled, quickly rinse under cold water, then use a clean and dry dish cloth to wipe away any sliminess. Using paper towel is also convenient. For dishes where some thickness (sliminess) is welcome, such as stewed dishes, this is a commonly used method.
Peel the satoimo to create a six-sided shape. Doing so increases aesthetic appeal, and is especially recommended for Japanese-style simmered dishes served for guests. First thinly slice off the top and bottom, then adjust each width while peeling vertically to create six even sides. Once a section is peeled, peel the section on the opposite side next, rather than the section beside, as this will make it easier to create equal-sized peeled sections.
