What foods should I avoid cooking in the Pressure Cooker?

Do not cook applesauce, cranberries, pearl barley, oatmeal or other cereals, split peas, noodles, macaroni, rhubarb, or spaghetti, as these foods tend to foam, froth and sputter, and may block the Steam Release Valve. Also, never deep-fry or pressure-fry in the cooker regardless of whether the Lid is on or off, as this is dangerous and can cause fire and serious damage. (Pages 3, 13)
