  8. Put into the oven, broil for a few minutes. Serve warm with blue cheese or ranch.


* your cauliflower will still be a bit crisp and cut well with a knife. If you prefer a softer cauliflower you may want to PC for 2-3 min. (Broiling will cook your cauliflower a bit more so keep that in mind.)

  1. Instruction no. 5 says set pressure to *1 minute. It should be what? Does foil/parchment go into pot after seaoning?

    1. 1 minute cook time will leave you with a nice crisp cauliflower. if you like yours a bit softer you may want to add 1 or 2 minutes additional cook time. The cauliflower can go directly onto the trivet with the foil/parchment. If it is easier for you to place it on the trivet with the foil still in underneath, that is also fine. 🙂

    1. Either or. You can leave it on for a bit easier clean up or place it on the trivet without it. I place without it. 🙂

  2. I was gifted an IP for Christmas, and am excited about learning what I can do with it!! And being from Buffalo, I love the flavor of anything Buffalo too. So, hope you don’t mind the slight criticism, but please capitalize Buffalo when speaking about food. The Buffalo flavor originated here, at Frank and Theresa’s Anchor Bar, home of the Buffalo wing. It has nothing to do with buffalos, they don’t have wings, lol! I realize younger folks probably just don’t know the history of the Buffalo flavor, and I enjoy sharing. Thanks for the rrcipe, I’ll make it this week!!!
