These noodles are made from the Konjac root, also called White Yam. They have a gelatinous texture and are a good source of the dietary fiber Glucomannan. It is a natural plant that grows in the mountains of East Asia. The plant is widely known in China and Japan for its health benefits. We use the extracted fiber from the plant's root and mix it with water to create delicious noodles. These noodles are a high-fiber food yet have no carbohydrates. The Glucomannan fiber in the noodles is a type of viscous fiber (soluble fiber). This is similar to what is found in chia seeds why they can absorb up to 50 times their weight in water. They have virtually no taste on their own but have a slight fish-like smell when packaged wet. This is due to the water they are packaged in and can be easily rinsed off. Directions Open the bag, drain the water, and rinse them really well for like 1 mins. Boil them in soup for 2 mins. Alternatively boil in water for 2 mins, drain, then you can use it to cook with these though: pad thai, salad, fried noodle or soup.
