This site is so informative that I had indeed put HOT water in my pan (had read some other thread where hot water is best) and had read about the sand and brick method as well. I guess my main concern using anything but water is the moisture of my meats. I do, after a few hours of smoke, wrap my meats in foil with some butter, apple juice or honey. I also spritz from time to time BEFORE I wrap. Is that enough to ensure a moist meat? Thanks for all the help fellas.
