Surprisingly, the best recipe for kalua pork that I have yet to find is also simple and uses the crock pot. Rock salt, liquid smoke and pork butt are the only ingredients. Rub butt with LS and then the rock salt. Throw in a crock pot and cook until finished.
While crock pot cookery isn't what a lot of us are used to, it can be a very simple and tasty meal at times.
