The word "cookies" comes from the dutch word kockie, meaning "little cake". Cookie is used only in North America, although Britain uses the term biscuits in the same content. English buiscuits are usually smaller than North American cookies and almost always are crisp rather than soft and chewy.
Cookies come in infinite shapes, sizes, flavors and textures. Crispness, softness, chewiness and spread are the characteristics that vary in each cookie. Cookies are classified by their makeup methods as well as by their mixing methods. No matter which cookie method you use, theymust be made of uniform size and thickness. This is essential for even baking.
