Coat shallow roasting pan with a rack with nonstick cooking spray.
Quickly prep the turkey by placing it on top of a large baking sheet with paper towels, remove the neck and giblets from inside the turkey.
Next, pat the turkey dry with a paper towel then stuff the turkey with the peeled citrus fruit, garlic cloves, ginger and scallions. Using kitchen twine, tie the legs together.
Coat the turkey with the grapeseed oil then season evenly with salt and pepper. Use your hands to massage the turkey and evenly distribute the seasonings.
Put the roasting pan in the oven and set a timer for 30 minutes. After 30 minutes, lower the heat to 350°F.
Roast for 1 hour then coat the turkey with the Ty Ling Hoisin Sauce using a pastry brush.
Continue roasting the turkey for 30 minutes or up to an hour until the turkey breast measures 160°F and the thigh/drumstick meat measures 170°F. Total roasting time should take about 2.5-3.5 hours.
Once the turkey comes out of the oven, brush the skin with a Ty Ling hoisin sauce and allow to rest for at least half an hour before carving.
