CANTONESE-STYLE TURKEY

Steps:

• Remove turkey from refrigerator and pat dry with paper towels. Place on a rack in a roasting pan and allow turkey to come to room temperature while you prepare the sauce.
• Swirl 3 tablespoons oil into a wok or large Dutch oven and set over medium-high heat until it begins to shimmer. Add garlic and ginger and cook, stirring, until golden, about 3 minutes. Add scallions, leeks and celery and cook, stirring often, until vegetables soften and cook down, 10 to 12 minutes.
• Add soybean sauce, orange peel, sugar, rice wine or sherry, white pepper, soy sauce and oyster sauce to the vegetable mixture, along with 2 cups water. Turn heat to high and bring to a boil, then lower the heat and allow mixture to simmer and thicken, 30 minutes. Remove from heat and let cool 20 minutes.
• Heat oven to 450 degrees. Spoon 1 cup of the sauce over turkey and spoon 2 tablespoons into its cavity. Tuck the tips of the wings under the bird and truss its legs together with kitchen string. Pour remaining sauce and 2 cups water into roasting pan and transfer to oven. Roast turkey, uncovered, for 30 minutes.
• Reduce oven to 325 degrees. Baste turkey with pan juices, and tent it with foil. Continue roasting another 1 1/2 to 2 1/2 hours, basting every 30 minutes with pan juices, until a thermometer inserted into the thigh registers 165 degrees. If pan starts to look dry, add hot water or turkey or chicken stock, if you have any, 1 cup at a time.
• Transfer turkey to a cutting board or platter and let rest at least 30 minutes before carving. Pour pan drippings into a small pot, adding enough warm water or stock to equal 1 cup, and keep warm on the stove.
• Increase oven temperature to 450 degrees. Grease a large sheet pan with 1 tablespoon oil, and arrange halved potatoes on the pan, cut side down. Season with salt and black pepper, and slide potatoes into the oven. Cook, undisturbed, until potatoes are tender and cut sides are nicely browned and crisped, 30 to 35 minutes.
• Remove pan from the oven, drizzle reserved drippings all over potatoes, toss and return to the oven to finish cooking, 5 minutes longer. Serve potatoes with turkey.
