Place the star anise, peppercorns, cloves, cinnamon stick, cardamom pod, tangerine peel, and water in a stew pot. Bring the mixture to a boil over high heat. Let boil until the poaching liquid is reduced to 4 cups.
Stir in the soy sauce and the sugar. Return the liquid to a boil.
Add the chicken breasts and reduce to a simmer. Poach the breasts until done, about 20 minutes.

I like to use this chicken as a base for chicken salad. The subtle spices impart a terrific flavor that turns a standby into a standup! Serve the chicken salad on a whole-grain roll with lettuce and apple slices.
