These went from dry to done in just a couple of hours thanks to the Instant Pot pressure cooker. It probably could have been done quicker but I was a little leery of the cooking tables. I have a vague memory of being disappointed in some pintos I cooked following their data. I decided to simmer them for an hour then give them an hour in the cooker. They cooked in chicken stock with a chopped onion, bay leaves, pepper, salt, dried thyme, and a couple chunks of cured ham.
