Konjac flour is made from the tuber of the konjac plant. It is a gum that can thicken liquids and stabilize emulsions; in alkaline mixtures it can also gel. It is often combined with other ingredients to improve their thickening and gelling.
It has been used in Japanese cooking for centuries and is used to make noodles as well as puddings and pastes. It is also unusual that it thickens at high temperatures instead of low ones.
Typically a 0.3-1.25% ratio by weight of Konjac will be used as a thickening agent.
