I have a hard time finding cooking times for certains items, especially grains, for a pressure cooker.The manual that came with my pressure cooker had times for veg, fruits, meats, and some beans but nothing more. I thought I would start a list and update it as I go. These are estimates because each cooker is different but at least it is a start...
BEANS
Black Beans - 9 to 11 minutes on high (assumes a pre-soak, can be done in cooker)
FRUITS
GRAINS
*note: it is usually recommended that you use a natural pressure release for grains. This often takes around 20 minutes or more depending on your cooker
Barley - Stovetop use 1:3 grain to water ratio, 40 minutes
Pressure cooker us 1:2 grain to water ration, 20-24 minutes
Quinoa - Stovetop use 1:2 grain to water ratio, 20 minutes
Pressure cooker 1: 1 1/2 grain to water ratio, 7-9 minutes on high
Rice (Brown) - Stovetop (I usually look at the package)
Pressure cooker 1: 1 1/2 grain to water ratio, 20-25 minutes on high
Rice (Brown, Short-grain, Organic) - Pressure cooker 1: 1 1/2 grain to water ratio, 30-35 minutes on high. This is a short grain, brown rice I get at costco and it takes longer than 20-25 minutes to cook.
Steel Cut Oats - Stovetop (check package, there are some quick cooking steel cut oats now)
Pressure cooker 1:3 (maybe 2 1/2) ration grain to liquid (you can use milk for part), 10 minutes on high
Wheat - Stovetop use 1:3 grain to water ratio, 120 minutes
Pressure cooker 1:2 grain to water ratio, 40-60 minutes
VEGETABLES
