1
The day before cooking, line an extra-large stock pot (about 30-gallon capacity) with a heavy large plastic bag.
2
Rinse the turkey, then place it inside the plastic bag.
3
In a large pot, combine 8 quarts of water, 2 cups of coarse salt, and 1 cup of honey, stirring until the salt and honey are fully dissolved.
4
Add 1 bunch of fresh thyme, the peeled garlic cloves, and coarsely cracked black pepper to the brine mixture.
5
Carefully pour the brine over the turkey, ensuring it is fully submerged. Gather the plastic bag tightly around the turkey and seal it.
6
Refrigerate for at least 12 hours, or up to 18 hours, to allow the brine to penetrate the meat.
7
On the day of cooking, position your oven rack in the bottom third and preheat to 350°F (175°C).
8
Drain the turkey well and discard the brine. Pat it dry inside and out with paper towels.
9
Squeeze the juice from the lemon halves into the main cavity of the turkey, adding the rinds and the remaining bunch of thyme.
10
Tuck the wings beneath the turkey and tie the legs together loosely to maintain its shape.
11
Place the turkey on a rack set in a large roasting pan and rub it all over with 2 tablespoons of olive oil.
12
Roast the turkey for 1 hour, basting with 1 cup of chicken broth halfway through.
13
Continue roasting, basting with 1 cup of chicken broth every 30 minutes, until the turkey is deep brown and a thermometer inserted into the thickest part of the thigh reads 180°F (approx. 2 1/2 hours more).
14
Once cooked, transfer the turkey to a platter and tent loosely with foil. Allow it to rest for 30 minutes before carving.
15
Meanwhile, prepare the gravy by placing the reserved turkey neck, heart, and gizzard from the brined turkey into a large saucepan.
16
Add 6 cups of water, 3 1/2 cups of chicken broth, coarsely chopped carrots, onion, celery, and a bay leaf.
17
Simmer over medium heat until the stock is reduced to about 3 cups, which should take around 2 hours.
18
Strain the stock into a bowl, reserving the turkey neck and giblets. Pull the meat from the neck and chop both the neck meat and giblets.
19
In a heavy saucepan, melt 5 tablespoons of butter over medium heat. Add 5 tablespoons of flour, whisking together for about 2 minutes to form a roux.
20
Gradually whisk in the turkey stock, whipping cream, and up to 1 cup of the reserved turkey pan juices, adjusting to taste for saltiness.
21
Simmer the gravy until it thickens to your desired consistency, about 5 minutes, while whisking occasionally.
22
Add the chopped turkey neck meat and giblets to the gravy and season with freshly cracked pepper to taste.
23
Serve the tender turkey slices drizzled with the velvety cream gravy, and enjoy the bounty of flavors.
