Baking is a method of preparing food using dry heat, usually inside an oven. During baking, ingredients undergo physical and chemical changes that transform a mixture of flour, sugar, fat, and other ingredients into products such as bread, cakes, and biscuits. Unlike some cooking methods, baking often requires careful control of temperature and time. In this lesson, you will understand the basic meaning of baking and discover how heat helps create the texture, colour, and structure of baked goods.
