Taiwanese three-cup chicken is named for the formula once used to prepare the dish: one cup each of sesame oil, soy sauce and rice wine. Not surprisingly, recipes no longer adhere to that ratio, but the name has stuck. Bone-in chicken legs that have been hacked into pieces are customarily used in this one-pan dish; we opted for boneless, skinless chicken thighs for easier prep and eating. Serve with rice and steamed or stir-fried vegetables.
