From my dad, the Thanksgiving turkey, gravy and mashed potato master.
1-2 teaspoons kitchen bouquet
1 tablespoon cornstarch
Turkey drippings (fat skimmed off) from bottom of roaster pan
Remove turkey from roaster pan. Empty contents of roaster pan into a large measuring cup or bowl. Skim out as much as much fat as you can. Reserve a couple tablespoons of it and discard the rest.
The roaster pan should have a sort of "crust" on it - this is yummy, scrape it up and keep aside!
In a sauce pan put in couple tablespoons of fat, to this add the cornstarch. Combine well, then slowly add the turkey drippings/juices from the measuring cup, whisking as you add. Add chicken broth (per your desired amount of gravy), salt, pepper, and kitchen bouquet. Bring to a boil, constantly whisking. As soon as it boils, turn off the heat and gravy is ready.
