I think all but the luckiest of us have cooked under pressure. Some of us have cooked under pressure night after night, trying to make a dinner that will be apreciatated.
But in this case, cooking under pressure refers to cooking using a pressure cooker.
Pressure cookers have come up in the world, now they are electronic or electric. They are filled with safeties to protect us from the specacular explosions of the past.
But try finding a basic recipe book for one. I think I've made it pretty well known that we are basci people, not fancy shmancy, so recipes using quail or dried apricots are not for us.
Give us the basic info on how to cook rice or spaghetti in one. How to cook a chicken breast, or better, a frozen chicken breast.
Those recipes would better serve us.
In the meantime, I've been searching You Tube. I've found some great recipes, never to be found again.
Now this is cooking under pressure, without the cooking!
