This recipe will yield 3 to 4 cups of gravy, depending on how much broth is used.
Substitutions for Dry Sherry: If you are wine drinkers, a dry white wine like sauvignon blanc or pinot grigio is the best substitute for dry sherry. If you happen to have a bottle of madeira or marsala in your pantry, those can be used as well. If you want a non-alcoholic option, you can use a splash of apple cider or additional broth.
Consistency Tips: For a thinner consistency, add additional chicken broth. If you've added to much broth and the gravy is too thin, mix about 1 tablespoon of cornstarch into ¼ cup water in a small bowl and stir to dissolve. Whisk the mixture into the gravy and allow to cook for another minute or two. Repeat if necessary to reach desired consistency.
To Richen the Color of Gray: Kitchen Bouqet works great to richen the color of gravies and sauces. A little goes a long way so just whisk it in a drop or two at a time, until you've happy with the color.
Reheating Tips: Leftover gravy will thicken quite a bit when refrigerated. To reheat, warm it gently in the microwave or in a saucepan on the stove, adding a little water or chicken broth to thin it to the desired consistency.
