This recipe has been designed to prevent the burn notice (food sticking to the bottom of the Instant Pot) and has been tested more than 10 times. If you get the burn notice it's likely because there isn't sufficient liquid in the sauce. We recommend adding an additional 1/2 cup of liquid and scraping the bottom of the Instant Pot before trying again. Be sure to follow the recipe instructions for layering the noodles to prevent burning.
