What is one key difference between baking and roasting?

The key difference highlighted in the correct answer is that baking is primarily used for foods that contain flour, while roasting is predominantly applied to meats and vegetables. This distinction is important because it relates to the methods and results associated with each cooking technique.

Baking involves cooking food by surrounding it with dry heat in an oven, which is particularly effective for items such as bread, pastries, and cakes, where flour is a main ingredient. The process of baking allows for the development of specific textures and flavors, characteristic of baked goods.

On the other hand, roasting also utilizes dry heat, but it typically involves larger cuts of meat or whole vegetables. The roasting technique aims to enhance the natural flavors of these ingredients, often resulting in a caramelized exterior while preserving moisture within.

Understanding this distinction helps in choosing the appropriate cooking method based on the type of dish being prepared.
