The amount of time it takes to cook ginkgo nuts is affected by a number of factors, including the variety and quality of the nuts, as well as the specific parameters of the pressure cooker. Using a pressure cooker to cook silver fungus can speed up the gelatinization process, making it quicker than traditional stewing methods. Put the silver fungus into the pressure cooker, add enough water, and cook under high pressure for about 30 minutes or so to achieve a better gelatinization effect.
