Pressure half time is the time required for the peak pressure gradient to reduce by half (1/2) which will correspond to a decrease in peak velocity by a factor of square root of two (21/2). Pressure half time of a regurgitant jet depends on the severity of the regurgitation and the compliance of the receiving chamber.
Remove the browned pork, place the meat trivet inside the cooker, then set the 4 pork pieces on the trivet. Drop the onion, apple and garlic cloves on top (don't worry if some fall through the trivet to the bottom). Pour beef stock in and seal cooker. Cook pork for 25 minutes. If you have a manual pressure cooker, start your timer after it starts to jiggle. In my electric pressure cooker, I can set the timer and then it won't start counting down until it's reached full pressure.
