I have been using this recipe for many years, my family loves this gravy and I have served it to dinner guests over the holidays and always receive rave reviews! --- you don't need to make this gravy using all pan drippings, if you do not have 4 cups of drippings you may mix with chicken broth to make the 4 cups, or it may be made with only chicken broth, please see note on the bottom of the recipe--- this may be made slightly ahead and kept uncovered on top of the stove until ready to serve, just whisk before using If you have any left over this gravy freezes very well or you may reduce all ingredients down to half and for a thinner gravy reduce flour by 1 tablespoon --- also see my recipe#314890 for more of my recipes visit www.kittencalskitchen.com
