Creaming Butter and Sugar
Incorporates air into the mixture, leading to leavening. The sharp sugar crystals cut through the fat creating air pockets that expand during baking.
Sifting Flour
Aerates the flour, removes lumps and helps distribute leavening agents evenly which affects the texture of baked goods.
Kneading Dough
Develops gluten, which gives elasticity and strength to dough, affecting the texture and chewiness of baked bread.
Folding in Egg Whites
Gently incorporates beaten egg whites without deflating them, adding air and volume for a light and airy texture.
Hydration of Flour
Water interacts with proteins in flour to form gluten, which provides structure to batters and doughs.
Melting Chocolate
Controlled heat allows chocolate to melt without burning. It incorporates smoothly into mixtures and solidifies upon cooling to add richness.
Caramelizing Sugar
The application of heat causes sugar to break down and reform into complex flavor compounds contributing to rich flavors and colors.
Using Baking Soda
Requires an acid to activate. Releases carbon dioxide () gas in dough or batter for leavening.
Using Baking Powder
Contains both an acid and base and activates with moisture and heat, producing for leavening.
Browning Butter
Heating butter causes the milk solids to brown and water to evaporate, resulting in a nutty flavor and concentrated fat.
Proofing Yeast
Hydrating active yeast and providing a warm environment allows it to ferment, creating gas bubbles for dough leavening.
Blind Baking
Pre-baking a pie or tart crust prevents it from becoming soggy when filled with wet ingredients.
Tempering Eggs
Gradually introducing hot liquid to eggs raises their temperature without causing them to curdle, ensuring smooth custards and sauces.
Using Yeast
Fermentation by yeast organisms produces and alcohol, causing dough to rise and adding flavor to baked goods.
Resting Dough
Allows for the distribution of moisture and relaxation of gluten strands, improving texture and handling of the dough.
Dutch-Process Cocoa Powder
Treated with an alkali to neutralize acidity, resulting in a milder flavor and darker color, and affects the leavening agents used.
Gelatinization
Heat causes starch molecules in flour to absorb water and swell, giving structure and firmness to baked goods.
Maillard Reaction
A chemical reaction between amino acids and sugars causes browning and complex flavor development in baked goods.
Egg Wash
Applying a liquid egg mixture to the surface of dough before baking adds shine and color due to protein coagulation and caramelization.
Fat Content in Butter
The percentage of fat in butter affects moisture and flakiness of pastries—higher fat content usually results in flakier textures.
Buttermilk in Baking
The acidity of buttermilk can tenderize gluten, add richness, and react with baking soda for leavening.
Recipe Scaling
Adjusting ingredient quantities while maintaining proper ratios is critical to keep consistent texture, flavor, and structure.
Strengthening Dough
Additional kneading and the addition of certain ingredients like sugar or fat can influence the strength and elasticity of dough.
Slow Baking
A gentle and prolonged baking process can lead to even cooking and moisture retention, often used for dense cakes or custards.
Aerating Agents
Substances like whipping cream or beaten egg whites introduce air into a mixture, contributing to a light and airy texture.
High Altitude Baking
Reduced air pressure at high altitudes requires adjustments to baking time, temperature, and ingredient ratios for texture and rise.
Toasting Nuts and Spices
Toasting enhances flavor through browning reactions and the release of essential oils.
Chocolate Bloom
Separation of fat or sugar due to temperature changes can cause a white coating on chocolate, which doesn't affect taste but can alter appearance.
Cold Fermentation
Performed in the refrigerator, it slows down yeast activity which can result in more complex flavors in dough.
Over-mixing Batter
Can result in excess gluten development, leading to tough or dense baked goods, rather than tender and airy.
