Doneness of smaller birds is determined in the following ways.
- Looseness of joints. The leg moves freely in its socket.
- Clear juices. Juices inside the cavity of a roasted bird are clear yellow rather than cloudy and red or pink.
- Flesh separating from bone. Muscles begin to pull away from bones, especially breastbone and leg bones. Excessively shrunken flesh means it’s overcooked and dry.
- Firmness to touch. Test with finger pressure as you would a steak. This method is especially useful for sautéed boneless chicken breasts.
- As for large roasted birds, testing with a properly calibrated thermometer is the most accurate way to determine doneness. Minimum temperature is 165°F (74°C).
