The browning sauce is a sauce that is used in meaty recipes to deepen the flavor and in soups and stews to darken the broth.
Browning Sauce consists of a blend of caramel color, vegetable concentrates and seasonings and is used traditionally in sauces and gravies like pan gravy.
If you want good tasting homemade gravy or stews, soups etc then using browning sauce can help you get that good taste.
You can make soups, stews etc without browning sauce but the addition of browning sauce makes it so much better.
You can make your own browning sauce with some simple ingredients or buy browning sauce already made at stores such as Walmart or just about any other grocery store should sell browning sauce.
I always use browning sauce when making gravy and stews or some soups and it makes it turn out a lot better.
