cheers everyone
i did have another problem - we put the pork on cos that takes longest to cook, but in hindsight - would you put all the meat on at same time and remove as it is cooked? or is that a problem cooking different things at once - all good learning i had to take top stack off to move ribs from the top to bottom with the pork - so i can add my chicken - the i will remove lid again to add chicken - i am figuring this is not a good move??
