This is a wonderful tamale filling! Full of flavor and a very traditional recipe. I have posted the recipe for the shredded pork separately. Please note that the amount of shredded pork used is an estimate. The recipe calls for a 2 1/2 pound pork butt. The amount of pork you end up with, will depend on fat, bone, etc. This recipe came from the Arizona Republic Newspaper and is absolutely wonderful. The directions for the masa dough for the tamales can be found on the package or see my recipe for fresh masa mix (much more work than the packaged masa mix). This recipe does not include the preparation or assembly of the tamales. It is just the recipe for the filling. Prep time does not include preparation of pork or assembly of tamales.
