I have used my new pressure cooker 2x ...one chicken and one roast....it was wonderful both times. But an old lady told me she never cooks brown beans in one cause they can blow up, due to all the gas from the beans??? Is this true?? I used to be scared of using one but I got one for christmas and want to cook beans in it. Is there any danger of them blowin up with beans?? I could use a good recipe if not....thanks !
