This is an optional ingredient in the recipe given for gravy. I use it very sparingly if I choose to use it at all. In truth, I believe all it adds is a depth of color, so, if the color looks right when the gravy is finished, I leave the Kitchen Bouquet out. When I choose to use it, it's just a drop, literally, or two perhaps. In the grocery store, I find it near all the extracts and baking ingredients.
