Getting a Weber to be stingy on the heat can be tricky no doubt and once those coals get going their hard to cool back down. For what its worth this is how I cope with getting the food away from the heat maybe it is something that will work for you. I drop a big ass piece of metal between the grates to seperate about 1/3 of the cooker to hold my coals with some bricks at the bottom to hold in place and take up space beneath the charcoal. This gives me a cooking area of indirect heat and keeps the need for fuel to a minimum. I load up the corner and just drop about 10 lit briquets on top. The smaller slots of metal just keep heat from hitting hard from the sides. I've had lots of luck with this set up, hopefully it will help ya out.
If it can't be smoked .... try frying it. It that don't work, it's probably best just left alone
And on the eighth day God created barbecue …. because he DOES love us and he wants us to be happy.
