Shirataki Noodles Overview

Shirataki noodles are made from konjac (glucomannan) fiber and contain very little to no digestible carbohydrates. They are a popular low-carb and keto-friendly substitute for pasta and rice noodles. Shirataki noodles have a neutral flavor but can have an odor in the package that rinses away. They work best when rinsed well and pan-dried before adding sauce.
