Instant chicken bouillon granules are dehydrated chicken stock that has been dried into concentrated granules. They are used in recipes and can be mixed with hot water to make a savory broth for soup or to drink.
To make dry bouillon, the broth is dehydrated and formed into cubes or granules. Substituting re-hydrated chicken bouillon is a quick and easy solution for cooks that do not have homemade chicken stock on hand.
The process of making chicken stock from scratch can be quite time consuming. The stock is made by boiling chicken, vegetables and seasonings for hours, and then straining out the solids, and keeping the broth to use in recipes.
