....cause the roast is cooking! I just bought a new 6 qt. Mantra SS Pressure Cooker. It's been on full heat for nearly 1/2 hour and it still doesn't seem to be "up to pressure". It's blowing vapor like crazy out the pressure guage, but it is also coming out the far side of the lid, too, so I don't think pressure has built up and sealed it. It says that once it builds up pressure, it will "hiss" and then I should turn down the heat until I get an occassional "puff" of steam out the regulator. I used to have an older pressure cooker with the gauge that rocked back and forth. I could TELL what that one was doing. I'm stumped on this one. I'm afraid to let it go TOO long for fear of it running dry. (2 cups water) Anyone have any ideas --- fast????!!
