Lay the turkey out on a sheet pan, place the pieces skin side up. Brush all over with oil. Sprinkle on kosher salt and pepper. Make sure the wings are in the middle of the pan.
Roast for 1 hour and 10 mintues or until the internal temperature of the white meat is at 155.
While the turkey cooks combine all the glaze ingredients minus the butter in a medium sauce pan. Bring to a boil and cook until it is thick enough to coat the back of a spoon about 15 minutes. Remove from the heat and whisk in the butter. Set aside.
Remove the turkey from the oven. Add the broth to the bottom of the pan.
Brush the glaze all over the turkey. Reserve 2-3 tablespoons for the gravy. Return the turkey to the oven.
Roast for another 10-15 minutes or until the white meat is at 165 and dark meat at 180.
Transfer the turkey to a platter to rest while you make the gravy.
To make the gravy
With a spatula break up all the bites stuck to the bottom of the sheet pan.
Then carefully pour the liquid into a fat separator. If you don't have one pour into another vessel and skim off whatever fat you can after you let it cool for 5-10 minutes.
Add the strained juices to pan. Add in 2 to 3 tablespoons of the leftover glaze.
Bring to a simmer and cook until thickened to your liking.
Slice the turkey and serve with the gravy.
Notes
If the glaze becomes too thick while you are waiting to use it, just gently reheat it. Or you can keep it on the stove on low, just make sure to whisk it before using.
