Plain Old Turkey Gravy
Add the broth to the skimmed drippings and reduce by one third. Remove from the heat and cook, stirring, until the mixture thickens. Add the sherry and Kitchen Bouquet, just to the desired color. Salt and pepper to taste. If too thick, add a bit more broth and cook for a few moments.
Sautees mushrooms make a nice addition to this gravy. If you are still unhappy with your efforts, try adding some Maggi seasonings liquid, a fine product from Switzerland. It is most helpful.
