After watching "In The Kitchen with David" on QVC and Bob Warden with his pressure cooker I have had the best beef stew in about and hour - maybe a little longer depending how much meat I buy. But I also throw in some red wine - helps break down the meat. But I pressure cook the meat first then later take out the meat cut it up, add all the vegetables (except the peas and corn) and bring it back to pressure for 5 more minutes. Release the pressure and add the flour to thicken it and then add the peas and corn.
