Close the lid of the pressure cooker and set the steam release knob to the Sealing position.
Press the Manual (or Pressure Cook) button and then the +/- button to choose 37 minutes. High Pressure.
When cook cycle ends, let the cooker naturally release pressure for 15 minutes. Then manually release any remaining pressure.
When the pin drops and it is safe to open the lid, do so carefully, facing away from you.
Gather up the two ends of the sling and VERY carefully lift the cheesecake pan out of the cooker and onto a cooling rack.
Leave covered for 10 minutes, then carefully peel off the foil/paper towel.
Cheesecake is done when it jiggles just a little when the pan is shook. You don't want waves. It will firm up in the fridge. If it looks to liquid, cover it back up and cook for another 5 minutes, and let naturally release for 15 minutes.
Leave on cooling rack until cool enough to put in the fridge.
Put the cheesecake, still in the pan, into the fridge to chill for at least 4 hours before serving. I prefer to make my cheesecake in the evening and let it cool overnight.
