In shallow saucepan wide enough to accommodate all ingredients in a single layer, place chicken, orange zest, peppercorns, carrot, onion, thyme and tarragon sprigs, and bay leaf. Pour in cold water to cover chicken by about 1 in (2.5 cm). Place pan on stove and heat on high. The moment water begins to simmer, reduce heat, and keep at a gentle simmer for 15 to 20 minutes. Do not allow water to boil. After time has elapsed, turn off heat, and remove chicken to plate and allow to cool thoroughly. Place in container with lid and refrigerate once cool.
