I had some rather tough sirloin, so I decided to just try it in the instapot and see. I could sear it in the pot, but I just browned it quickly in the fry pan and then put it in about three quarters of beef broth.
I added these spices
Worchester Sauce
granulated garlic
black pepper
Benson's masterpiece meat spice
I put in a yellow onion cut in pieces and topped the steak and onion with small, already peeled carrots.
I set the time for five minutes. I then let the steam escape slowly for five more as that is supposed to not make it so tough.
RESULT: The steak was just as tasty as pan fried, but not much less tough. I think 5 minutes is too much for medium rare. It ended medium. Carrots cooked well. Spices were good. I used Benson's salt at the table.
