Step 1
Stir the onion, ginger, garlic, star anise, white wine, salt, pepper, 2 tablespoons vegetable oil, rice vinegar, and chicken together in a mixing bowl. Cover, and marinate in the refrigerator 4 to 6 hours. Meanwhile, place the potatoes into a large pot and cover with salted water. Bring to a boil over high heat, then reduce heat to medium-low, cover, and simmer until tender, about 15 minutes. Drain and allow to cool before cutting in half.
