Step 1Rub salt into all surfaces of the ribs. Set aside for 1 hour.
Step 2Combine the soy sauce, brown sugar, star anise, peppercorns, ginger and garlic in a stockpot. Add 10 cups water and bring to a boil. Lower heat to a simmer and add the ribs. Simmer, covered, 45 to 60 minutes, until the flesh starts to pull away from the bones. Set aside to cool while heating the grill.
Step 3Combine the vinegar with minced garlic and sugar and set aside.
Step 4Lay the ribs on the grill and cook 10 to 15 minutes, turning often, until charred and tender. Cut into individual ribs and serve with the vinegar sauce for dipping.
