Pot roast and gravy
I used a 3 pound arm roast (any chuck cut will do, bone-in) that was about 2" thick, and still partly frozen. Don't trim off all the fat. It is not necessary or beneficial to brown the meat before cooking.
Drizzle 1-2 T soy sauce over both sides of the roast.
In the pressure cooker, melt 1-2 T butter and saute 2 med onions, 1 large carrot and 2 stalks of celery, all chopped. Add 2 T tomato paste and 1/2 c dry red wine and bring to a boil. Stir in 1 1/2 c beef broth and 2 bay leaves. Put the roast on top of the broth. Lock the lid in place. Over high heat, bring to high pressure; reduce heat and maintain high pressure for 1 hour. Release pressure naturally (beef will be tougher if you quick release).
Remove the beef to a platter (yes, it will fall apart!!!). Remove the bay leaves and discard. Strain out the solids and degrease the liquid. Puree liquid with solids and return to pot. Bring to a boil. Reduce to simmer and add 2-3 T cornstarch in an equal amount of cold water, well mixed, to thicken.
