Recent marinara sauce recipe by Ivy Manning, posted on Instant Pot's site. I have not tried it yet. But you know I will, because I bought this Instant Pot thing during Cyber Week and I am still trying to find ways to justify this purchase.
I have some frozen tomatoes thawing out in my test kitchen. fwiw, I never peel tomatoes. I make the sauce then run it through the blender. Or, you could use an immersion blender, too.

Ivy Manning's Instant Pot Italian cookbook was recently released and it's supposed to be pretty good. Barbara Schieving of pressurecookingtoday.com also has a great new cookbook of recipes that actually work. No affiliation with either person or their business ventures.
