re: Pressure cookers
I had a deposition recently where the 3-gal pressure cooker in a soul food restaurant (used to cook greens) did explode. I looked at the pictures....WOW! It was kitchen carnage. It blew the salamander (unit used for heating food/keeping it warm on a shelf above the stove) to bits. The lid became like a missile and took out the back wall creating a hole into the next establishment you could crawl through, a TV fell off the wall, and the iron grill grates of the stove were turned into confetti. The pot itself was fine, but the lid was in 10+ pieces (mind you, it was probably 1" thick or so). The lawsuit was about one of the restaurant patrons (closest to the kitchen pass-through window) claiming loss of hearing. Considering the deep fryer was next to the stove, they're very lucky there wasn't a huge kitchen fire.
Anyway, it got me to thinking that maybe I don't want to inherit my mom's pressure cooker....especially since it's probably about as old as I am and -- like me -- possibly structurally unsound (it sounds to be about as in the same condition as the one in the restaurant: The polish off the chrome and really old). I may grumble when bumped, but at least I don't explode.
The pressure cooker exploded most likely NOT because someone bumped it, but because it was perhaps overstuffed and some bit o' green got stuck in the pressure outlet...the investigators are still trying to figure that one out.
I keep seeing the new electric pressure cookers being touted by celebrity chefs on Home Shopping, but at present I'm not feeling safe about 'em. Pity, because nothing makes an artichoke quicker than a go-round in a pressure cooker.
