Correct measurement for chicken broth powder to water
The amount is totally subjective. In general, I prefer lighter amounts in soups and heavier amounts in any flavorings (I.e collard greens or broth powder used as spice.) Cooking is really more art than science, so precision is not usually my top priority. For whatever you are cooking, and if it is safe to do so, add a small amount, stir and taste. Chicken broth powder usually has a high sodium content, so treat it as flavored salt. If more "saltiness" is desired, add a teaspoon, stir, taste, and repeat.
