1. Preheat oven to 425°F.

3. Put turkey on a rack set in a large flameproof roasting pan. Roast turkey in middle of oven 30 minutes.
4. While turkey is roasting, blanch onions in boiling water 1 minute and rinse under cold water. Peel onions, then toss with 1 tablespoon melted butter and salt and pepper to taste. Toss apples with 1 tablespoon melted butter and salt and pepper to taste in another bowl.
5. Reduce temperature to 350°F.
6. Brush remaining 1/4 cup melted butter over turkey and roast 30 minutes more.
7. Baste turkey and scatter onions around it, then roast 30 minutes more.
8. Baste turkey and add apples to roasting pan. Roast another 1 to 1 1/2 hours, or until a thermometer inserted into fleshy part of a thigh registers 180°F.
9. Transfer turkey, onions, and apples to a heated platter, leaving juices in pan.
10. Remove skewers and discard string.
11. Let turkey stand at least 30 minutes, up to 4
12. Skim fat from pan juices and reserve 1/4 cup fat.
13. Pour pan juices into a 2-quart glass measure and add enough turkey giblet stock to make 4 1/2 cups total. Set pan to straddle 2 burners.
14. Add 1 cup stock mixture and deglaze by boiling over moderately high heat, stirring and scraping up brown bits.
15. Add remaining 3 1/2 cups stock mixture, cider, and vinegar and bring to a simmer.
16. Transfer to glass measure.
17. Whisk together reserved fat and flour in a large heavy saucepan and cook roux over moderately low heat, whisking, 3 minutes.
18. Add hot stock mixture in a fast stream, whisking constantly to prevent lumps, then simmer, whisking occasionally, until thickened, about 10 minutes.
19. Stir in any additional turkey juices from platter and season gravy with salt and pepper.
20. Pour gravy through a fine sieve into a gravy boat.
21. ·Onions can be blanched and peeled 2 days ahead and chilled, covered. ·We recommend making the turkey giblet stock and fried sage leaves ahead, though they can be prepared while the turkey is in the oven.
