Michelle's Rice Pudding

I have tried 3 times with no success at making rice pudding in my new digital pressure cooker. Everyone swares it can be done on the internet, which makes the failure even worse!
Anyways, my experience with THIS recipe is that is turns out awesome every time. It is a great dessert to use those food storage staples, powdered milk, and rice.
