Mix together sage, salt, pepper, and garlic.

Rub the mixture over the pork. Add it to the slow cooker and pour 1/2 cup water in the bottom of the slow cooker. Cook on low for 6 to 8 hours.

One hour before the pork is cooked, put the brown sugar, cornstarch, balsamic, water, and soy sauce in a sauce pan. Bring the mixture to a bubble over medium heat. It will get thick.

Pour half of the glaze over the pork. Reserve the rest to serve alongside.

Cook the pork for another hour.

Shred the pork with a fork. It will fall apart, it is so tender.

Serve with the remaining glaze.
