1. Preheat the oven to 375˚F.

2. Bring a large pot of water to a boil. Add ribs, ginger, and garlic. Bring back to a boil and let simmer for 30 minutes. Turn off the heat and let sit for about 10 minutes.

3. In a saucepan, combine hoisin sauce, vinegar, soy sauce, five-spice powder, and brown sugar. Heat until sugar is dissolved and sauce is smooth and thick. Then reduce for about 2-3 minutes on medium heat. Set aside.

4. Drain ribs and pat dry with some paper towels. Line a 36 x 18-inch rimmed baking sheet with aluminum foil. Place ribs on a baking sheet and brush them all over with the marinade.

5. Place in oven and roast for 1 hour, basting with a pastry brush every 15 minutes with more marinade.

6. Serve on a platter and brush extra sauce on top.
