I assume you did just a flat, based on the weight. I have found that flats cook so fast using the hot-n-fast method, they do not render as well as a slower cook. I am still trying to figure out doing a flat only cook. The last one I did was the closest to being the way I would like so far. I did not foil and really paid attention to the final half hour or so. I did not do temperature other than to tell when to start probing. Once it felt pretty soft, not as easy to probe as a slower cook, I pulled, panned and foiled. Then put back onto cooker as it cooled, coals going out. After 45 mins, pulled it out and sliced. It was better.
me: I don't drink anymore
Yelonutz: me either, but, then again, I don't drink any less
