For pressure cookers: Cook on high pressure for 35 minutes: Lock pressure-cooker lid in place and bring to high pressure over medium-high heat. As soon as pot reaches high pressure, reduce heat to medium-low and cook for 35 minutes, adjusting heat as needed to maintain high pressure. Remove pot from heat and allow pressure to release naturally for 15 minutes. Quick release any remaining pressure, then carefully remove lid, allowing steam to escape away from you.
