Shortbrea is a type of biscuit (cookie) which is traditionally made from one part white sugar, two parts butter, and three parts oatmeal (although plain white flour is common today, and other ingredients like ground rice or cornflour are sometimes added to alter the texture). Shortbread is so named because of its crumbly texture (from an old meaning of the word short). The cause of this texture is its high fat content, provided by the butter. The related word "shortening" refers to any fat that may be added to produce a short (crumbly) texture.
