Granny, my mom could make anything tender and juicy in a pressure cooker. I still use it for Grandma Steak (round steak with lots of onions) so the kids have something to remember about her. And mashed potatoes with it. Don't forget the gravy.
We made oyster stew on Christmas Eve. I hate the oysters themselves.
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??
