pressure cookers scare the poo out of me and I can never get them to work right. But love eating other people's pressure cooked meals Other then round steak IMH grind it up for hamburger. Mom's would be tender but OMG so over cooked dry and grey unfortunately dad loved it. I likes my steak with a little life in it the rare side of medium rare please. Oysters have gotten expensive lately did you use fresh or canned??
