Pressure releases
natural release, where you let the pot cool for a specific amount of time before opening the valve (do nothing). this allows the steam inside to cool and condense back into liquid which in turn reduces the pressure. A full nr is where you leave it until the pin drops. usually chicken needs a 10 min nr, and beef 15. with meat, if you manually open the valve right away, the pressure is released at such a high rate it can literally depressurize the juices right out of the meat. Controlled release is also a good one to know how to do. It's where you open the valve only a tiny bit so a very weak stream of steam escapes, or you repeatedly open and close the valve in short bursts. you do this with anything starchy, or with a full pot, or anytime your pot tries to spew food out the valve. It happens, you will see it posted time and again! - It just doesn't ever need to happen If it does, just close the valve, don't let it continue to make a mess, then do a controlled release. if keep warm function is on, you will have a handy timer as it count back up the lapsed time since cooking. keep warm itself doesn't kick on until the temp has lowered to 140 degrees!
