Baking ingredients are the essential components used to create baked goods like bread, cakes, and cookies. Common ingredients include flour, sugar, eggs, butter, and baking powder. Each ingredient plays a specific role; for example, flour provides structure, while sugar adds sweetness and moisture. Other important ingredients include yeast, which helps dough rise, and vanilla extract, which enhances flavor. Salt is often added to balance sweetness and improve taste. Understanding these ingredients and their functions is crucial for successful baking, as they work together to create the desired texture and flavor in the final product.
