Place pork roast in crock pot with 1/2 cup water, salt and pepper. Cook on low for 6 to 7 hours until roast is tender or high for 4 hours. Remove roast and drain off liquids. (Reserve some of the liquid) Shred roast with a fork and put back in crock pot.
Mix remaining ingredients together in a bowl with a wire whisk along with 1/2 cup of drained pork juices. Pour over roast and cook for at least 2 more hours in crock pot on low. Roast should be wet but not soupy. If it looks too dry add a little more of the juice you drained off.
Notes
This can be done with beef roast, too. Makes 10 to 12 servings and keeps well in the fridge for 4 to 5 days.
