The wife picked up a couple of chuckies at the grocery store the other day (buy 1 get 1 free). They are small, approximately 2 1/2 lbs. each. I'd like to do them Saturday for dinner about 7 pm or so. These will be done in a charcoal Brinkman Gourmet that I just got. I screwed up on cutting my dampers ( didn't leave enough space between the holes to cover when closed) and will be using almost as purchased. I did get a new therm in the lid. When I seasoned it with a pan of water and no food temps got up around 375. But that was with quite a bit of fuel in the pan. I figure I can get temps down by limiting the amount of fuel in the pan, but if I get down to about 250, how long should these things take?
