Lotus root is hard and contains more starch, so it is difficult to cook. If you cook in a common pot, it usually takes about 30 minutes-1 hour to cook completely soft and rotten. If the lotus root is cooked in a pressure cooker, it only takes about 10-20 minutes.

The strong pressure in the pressure cooker will shorten the cooking time of food, so it is not suitable for long-term stewing. When cooking lotus roots in a pressure cooker, first check whether the exhaust hole of the pressure cooker is unobstructed, and then add lotus roots. The amount of water should not exceed lotus roots to avoid uneven heating.
