When I was growing up my mom had a pressure cooker and my grandma had a pressure cooker; so when I found a used one, about 15 to 20 years ago, I just had to have it. I believe I paid 3-dollars for it and was pretty excited until I realized something was missing...Which was the pressure control that sits on top. After searching for several months, while on a road trip, I located one at an Ace Hardware store in Oklahoma. The price was a shocking 10-bucks; but without it the pressure cooker wouldn't work.
Thankfully finding a book was cheaper, 1-dollar at a junk store.
Over the years I found I seldom used my pressure cooker; until recently when I was on a quest for a juicier roast and began searching the web for ideas. Now I am truly hooked on pressure cooker cooking.
To cook a great roast sprinkle with salt, pepper and garlic powder; sear each side in a little oil; be sure to sear the roast in the pressure cooker and not a separate pan.
My book recommends cooking roast at 10-pounds for 45 to 60 minutes. I like cooking for the full 60 minutes; the meat comes out so tender and juicy.
