0sound91 11 years ago I have always done the same as M4industries, but any kind of pop seems to work. One that my group usually did included cherry coke. Also, I have always used the cheap Jiffy cake mix as my top and sometimes bottom. Always place two more coals on the bottom than the width, and two less on top. Example, if you are using a 12" dutch oven, ten coals on top, and fourteen bottom.
