When the cooking program ends, let the pressure release naturally for 20 minutes, then move the Pressure Release to Venting. Open the pot and, wearing heat-resistant mitts, grasp the handles of the steam rack and lift the pan out of the pot. Uncover the cheesecake, taking care not to get burned from the steam or to drip condensation onto the surface.
Use a paper towel to dab off any excess moisture that may have settled on top of the cheesecake. The cake will be a bit puffed up and uneven at first, but it will settle and even out as it cools.
