The original stovetop pressure cooker recipe from November 2000 Southern Living (http://www.geniuskitchen.com/recipe/sl-roast-with-onion-and-mushroom-gravy-6-qt-pressure-cooker-513644) needed to be tweaked to succeed in the popular electric pressure cookers available today (2018). While I was tweaking, I did away with the can of condensed mushroom soup and replaced it with a mock "Condensed Cream of Whatever" recipe (thank you, Jill Selkowitz [aka "This Old Gal"]), and sauteed an entire 8-ounce carton of cremini mushrooms (aka baby bella mushrooms) with a splash of dry sherry to suit us mushroom lovers (we vote for 1 pound of mushrooms next time!). However, you may use a can of Condensed Cream of Mushroom Soup if you wish. By the way, Cook Time includes time for pressure cooker to come to pressure and then depressurize. It is important to allow a full natural release (pin going down without any intervention) for the texture of the meat. You will get A LOT of gravy.
