Preheat oven to 400°F (200°C). Squeeze juice from ½ of the orange; set aside.

Roast turkey 45 minutes.
Decrease oven to 375°F (190°C) and roast 1 hour. Baste turkey and turn pan in oven. Continue roasting until meat thermometer inserted in thickest part of thigh reaches 180°F (90°C), about 1 hour. Remove turkey from pan and keep warm. Skim fat from pan drippings, then pour drippings into measuring cup. Add enough water to bring total liquid to 2 cups (500 mL).
