Sounds interesting. Question - if you make a soup or stew or something that gives off a lot of fat, and you want to eat it that night, how do you skim all the fat off? I've never had much luck with a lettuce leaf, or a spoon. A long time ago I had a top of Stove pressure cooker and used it a few times, but then I couldn't get the fat off. I'd end up putting the food in the frig over night til the fat got hard and could be lifted off, which I figured I didn't need a pressure cooker for. It was a long time ago. I gave it to a friend maybe 30 years ago and he still uses it and just had to change the gasket about 15 years in. Never a mishap. Thanks for the info.
