The Quiet Difference Between Stock And Broth

They both come out of a pot of bones and water, but stock and broth want different things. Knowing which one a recipe needs is half the battle.

Stock and broth share a basic outline of bones, water, and time. What separates them is what each one emphasizes. Stock leans on collagen, so a long, low simmer pulls gelatin out of joints and feet and leaves you a liquid that sets to a jiggle in the fridge. Broth leans on flavor, so a shorter, hotter cook draws more savor out of meat and vegetables but builds less body.

A French braise wants stock, because it builds its own sauce as it reduces and the gelatin is what makes that sauce cling to a spoon. A clear noodle soup wants broth, because the noodles supply the body and the liquid needs to taste of aromatics rather than gelatin. Use the wrong one and a perfectly cooked dish will land slightly off the mark.

A well-stocked freezer holds both. Pour stock into ice cube trays for quick pan sauces, and freeze broth in quart bags for soups. Label each by what it is and you will never again reach into the freezer and grab the wrong one.
