Rinse the dried soybeans lightly and soak them in 800ml of water for about 6 hours.

Place the soaked soybeans into a pressure cooker, cover, and heat on medium until pressure builds. Once pressurized, reduce to low heat and cook for 7 minutes. Turn off the heat and let the pressure release naturally before opening the lid. Drain the soybeans.
