Miso Konnyaku

Konnyaku is a Japanese traditional food.

Konnyaku is a traditional Japanese jelly-like health food made from a kind of potato called "Konnyaku potato" and calcium hydroxide or oxide calcium extracted from eggshells. The Konnyaku potato is native to Indonesia and is a kind of herbaceous perennial plant called "Amorphophallus Konjac"(K. Koch). Konnyaku potatoes are cultivated for food only in Japan, but wild forms grow naturally in Southeast Asia and China.

Japanese have been eating it over 1500 years. It was originally introduced to Japan as a medicine in the sixth century and has been eaten for almost 1500 years in Japan. It is a totally natural food. Ninety seven percent of Konnyaku is water and three percent is Glucomannan, or dietary fibre. It is also rich in minerals and very low in calories.

It does not have fat, it is rich in dietary fibre and is low in calories. Moreover, it has recently been found that it normalises the level of cholesterol, prevents high blood pressure and normalises the level of sugar in the blood. Because of these scientific findings, it has been perceived as a excellent health food in Japan.

In Japanese cuisine, konnyaku appears in dishes such as oden. It is typically mottled grey and firmer in consistency than most gelatins. It has very little taste; the common variety tastes vaguely like salt. It is valued more for its texture than flavor.

Japanese konnyaku jelly is made by mixing konnyaku flour with water and limewater. Hijiki is often added for the characteristic dark color and flavor. Without additives for color, konnyaku is pale white. It is then boiled and cooled to solidify. Konnyaku made in noodle form is called shirataki (see shirataki noodles) and used in foods such as sukiyaki and gyudon.
