Clean the crust residue out of the food processor.
Add the cream cheese, sugar, and vanilla and process until smooth and creamy.
Pulse a several times until well combined.
In a microwave safe bowl, add the white chocolate chips and heavy cream. Heat for 25 seconds in microwave. Stir very well and put back in for another 25 seconds. Stir very well again. It may take a couple minutes of stirring to become creamy, which is what you want.
Let it cool to luke-warm, then stir in the sour cream (which helps cool it), and add it to the cream cheese mixture.
Add the peppermint extract and the corn starch. Pulse several times to combine. Then process for a minute to make it smooth and creamy.
Add the eggs last. Pulse just until combined. If you whip the eggs too much the cheesecake will puff up and won’t have the right consistency.
Take the crust from the freezer and pour the filling into the pan.
Cover the pan with a paper towel, then with a piece of foil. Crimp the edges around the pan so it stays taut and secure.
Lay the sling out and set the pan on it, centered. Gather up the two ends and very carefully lift the pan and set it in the pressure cooker, leaving the sling with it. Just fold over the two ends of the sling on top of the pan.
