Elephant yam, also known as konjac (Amorphophallus konjac or Amorphophallus rivieri), native to Asia. The konjac tuber has been used for centuries as an herbal remedy and to make traditional foods such as konjac jelly, tofu, and noodles. More recently, purified konjac flour, or GM, has been used as a food stabilizer, gelling agent, and supplement.

What grocery stores in Austin are stocking elephant yams?
Any restaurants in town cooking with elephant yams?
