Go easy on how much liquid you put in.
I cannot stress this enough! As a two-time chili competition winner, I had grown accustomed to putting extra homemade stock when cooking on the stove top. Do not do this in your Instant Pot! It doesn't lose moisture quite like when you're cooking on the burner. I learned this the hard way after opening my Instant Pot when my fiancé said, "Next time, we shouldn't use both containers of stock! It's watery." To which I replied, "Yeah, I didn't!" Then silence. You live, you learn, right?
