Pressure cooks much quicker. All these people who are saying several hours are wrong. If its frozen solid I can cook stew meat in 30 minutes once its up to pressure and the time starts counting down. You need to use the meat rack and put at least 1 cup of water. Once the meat is cooked, use the broth and add the cream soup and heat thru under the sauté setting, not under pressure. You have to create steam to have the pressure. If your sauce is too thick, the pot will not seal and be under the pressure. It will fail to cook properly.
