Cat head biscuit

In the United States, a biscuit is a variety of baked bread with a firm, dry exterior and a soft, crumbly interior. In Canada it sometimes also refers to this or a traditional European biscuit. It is made with baking powder as a leavening agent rather than yeast, and at times is called a baking powder biscuit to differentiate it from other types. Like other forms of bread, a biscuit is often served with butter or other condiments, flavored with other ingredients, or combined with other types of food to make sandwiches or other dishes. Biscuits, soda breads, cornbread, and similar breads are all considered quick breads, meaning that they do not need time for the dough to rise before baking. Biscuits developed from hardtack, which was first made from only flour and water, with later first lard and then baking powder being added. The long development over time and place explains why the word biscuit can, depending upon the context and the speaker's English dialect, refer to very different baked goods.
