Little off task from the original question, but what kind of pressure cooker do you have? I''m reading all sorts of different things that you need a variable pressure, pressure cooker in order to do meats and fruits/veggies. Presently I have one (from e-bay, great price) that is a constant 15 lbs pressure. From the sounds of it, I can''t can fruits or veggies unless I have a 5, 10, 15 lb variable cooker. Does this sound right?
