(2004). On Food and Cooking: The Science and Lore of the Kitchen. New York: Scribner. Flour Adds to the chewiness, but since it is not melted there is still structure to the cookie. Slightly puffy/cakey retain moisture inhibits too much gluten formation Since the butter is still slightly solid it creates steam while baking acting as a leavening agent as well White Sugar harder/chrunchier cookie Browns when baked colorless/ordorless neutral flavor Butter Helps create the gluten All-purpose flour = soft flour (not too much gluten) Doucleff, M.
