"The pork usually gets slathered in barbecuse sauce and frozen..."

If you are using one of the common bottled barbeque sauces, you might want to a can of Del Monte "Sloppy Joe Sauce" instead. Be sure you get the 15 oz. can marked "Hickory" and "Bold BBQ taste!". My local supermarket did not stock it and I had a hard time explaining that other brands were just not the same.
It is a bit sweet which is just what I like.
