Mix all of the Rub ingredients together. Rub the pork all over with the spice mixture. It will make more than you will probably need. Leftover Rub can be stored in an airtight container for up to six months. Cover roast and refrigerate for at least an hour or up to 24 hours.

Preheat oven to 300 degrees.

Place pork in a roasting pan. Then bake for about 4 hours or until the internal temp reaches 170 degrees.

Shred with two forks. Add salt and pepper to taste.

To serve: tuck meat into corn or flour tortillas and add your favorite toppings.
