I haven't tried this one yet, I'm putting it here for safe-keeping. Looks good, and interesting, and would be good to do when turkey parts go on sale. This recipe is from B.J.'s Market & Bakery in Chicago.
To make wings: heat oven to 350°; brush wings with vegetable oil and place in a large roasting pan; stir together salt, pepper, garlic powder, poultry seasoning and onion powder in a medium bowl; sprinkle over turkey wings.
Bake until browned, 45-60 minutes.
To make sauce: melt butter in a large heavy saucepan or dutch oven; add celery and onion; cook over medium-low heat until soft but not browned, about 5 minutes; stir in thyme and pepper; cook 1 minute; add flour; cook, stirring constantly, until light brown, about 5 minutes; slowly whisk in broth.
Heat liquid to a boil; reduce heat and simmer uncovered 20 minutes.
Strain sauce through a sieve and return to the saucepan; slowly whisk in milk and stir constantly until sauce returns to a simmer.
Pour sauce over turkey wings; cover and cook until tender, about 1 hour.
