I want to use my Presto 16 quart Pressure Cooker to make a mess of Pinto Beans, Black Eyed Peas and Pork Neck Bones. I know I think I should soak the beans and peas and precook the neck bones and put them in my cooker with seasonings but not sure if I only fill cooker half way then add pressure. But not sure on how long to cook, and don't know if it is 5, 10, or 15 pounds of pressure for how long.. I'm a beginner to pressure cooking and just some help to make this delicious meal for my hard working fiance along with Butter Milk Cornbread (Which I got that part right LOL).. just need someone to please help me shed some light on the Pressure Cooker for me. PLEASE HELP!!!!!!
