Baking is a method of cooking food with dry heat, usually in an oven. It is used for bread, cakes, biscuits, pies, pastries, casseroles and many other foods.
Baking is both a practical food process and a craft. It depends on ingredients, heat, timing, moisture, structure and chemical change. Small differences in flour, temperature or mixing can change the final texture.
Heat and Structure
During baking, heat moves from the oven into the food. Water turns to steam, fats melt, starches gelatinise, proteins set and sugars brown. In bread, these changes turn a soft dough into a loaf with a stable crumb and crust.
The Maillard reaction is one of the processes that gives baked foods colour, aroma and flavour. It happens when reducing sugars and amino acids react under heat. Caramelisation can also contribute sweetness and browning, especially in sugar-rich foods.
Leavening
Many baked goods need lift. Yeast, sourdough cultures, baking powder, bicarbonate of soda, steam, beaten eggs and trapped air can all help create rise.
In yeast bread, fermentation produces carbon dioxide. Gluten helps trap the gas and gives the dough stretch. In cakes and biscuits, chemical raising agents or creamed fat and sugar may provide lighter texture.
Common Stages
The exact method depends on the food, but many baking processes include:
- measuring ingredients
- mixing or rubbing in
- kneading, folding or creaming
- resting, chilling or fermenting
- shaping or panning
- baking at a set temperature
- cooling before cutting or serving
Cooling matters because structure continues to set after food leaves the oven. Cutting bread too early can make the crumb gummy, while some cakes become easier to handle after cooling.
Bread Baking
Bread baking usually combines flour, water, salt and yeast or sourdough culture. The dough is mixed, developed, fermented, shaped, proofed and baked. Time and temperature influence flavour, crust, volume and crumb.
Different bread styles use different hydration, grains and fermentation. A baguette, sandwich loaf, focaccia, naan and rye sourdough all rely on baking, but they do not use the same dough structure or heat treatment.
Cakes, Biscuits and Pastry
Cakes often rely on a balance of flour, fat, sugar, eggs and raising agents. Biscuits and cookies use less liquid and often aim for crispness, chew or snap. Pastry depends heavily on fat, temperature and handling.
In laminated pastry, layers of dough and fat are folded to create flake. In shortcrust pastry, fat is rubbed into flour to limit gluten development and produce a tender texture.
Home and Commercial Baking
Home baking allows flexibility and small batches. Commercial baking uses controlled processes, specialist ovens, proofers, mixers and quality checks to produce consistent results at scale.
Both forms depend on the same basic science. The difference is mainly in scale, equipment, consistency and the amount of process control.
