Homer has that “ate the canary” look but I can assure you there are no canaries stopping by the feeder.

I cooked a pork shoulder in a 200 degree oven overnight in a covered pot.  That big Dutch oven is good for projects like this.  I added the usual seasonings and also a bottle of regular Coke.  It turned out fairly well.  After pouring off the excess liquids, I boosted the temp to 350 and returned the roast to the oven, uncovered, to get a little more color on the meat.  The reserved liquids were skimmed of  fat and reduced in a separate sauce pot before adding them back.
