Thanks Everyone!
For the tips, suggestions, comments and recipes.
Nabbed an Magefesa "Rapid II" off fleaPay awhile ago, but didn't get to try it out until Sunday night. Made corned beef (no cabbage nor potatoes, served with rice and veggies instead), and it came out a treat.
Wasn't really going to do CB, but it was one of the few cuts of meat at the market one could do in a PC that are "easy" for a start. Also if one had time would rather have gone over to Whole Foods for an "organic" brisket, as the nitrate, phosphate, sodium filled versions sold a the supermarket aren't something I'd eat often,but for one night could deal.
Used a combination of recipes from Ms. Vicki and a copy of "Better Homes Step by Step Cookbook". The cookbook one has had since "hope chest days" and used their version of a CB dinner (with carrots, potatoes, etc..) before and really like the brown sugar and mustard glaze applied after cooking the brisket. Miss. Vickie's site was many to suss how to get the project done, the manual from Magefesa is stingy with details and such.
All and all am that well pleased with my first effort at CB in a pressure cooker. It was done in about 50 minutes, was "falling apart tender" and gobbled up quickly, though there is enough for sandwiches or leftovers.
The Magefesa "Rapid II" PCs came highly rated in their day, but aren't imported to the States anymore (they are made in Spain). Unit comes up to pressure quickly and holds temp quite easily. The only tricky part for me at first is learning how to set the pressure regulator. You see there is a knob allowing one to set pressure at "I" or "II", low or high if you will, which when various pressure levels are reached at each setting (again, I and II), give four different PSI levels (8,10,12 and 15). Manual does not tell you set the pressure regulator before closing the lid. You then wait for steam to build, pushing up the indicator to whatever level (I or II) you need. Yes, this is not like your simple "jiggle" top PC.
Have to say quite unlike jiggle top pressure cookers, this thing is quiet. You wouldn't know anything was going on aside from a hissing sound every now and then as the system regulates pressure.
