What happens during the shortening process in cooking?

During the shortening process in cooking, particularly in baking, fat is incorporated into flour, which helps to inhibit gluten formation. As fat coats the flour particles, it creates a barrier that prevents gluten strands from developing fully, resulting in a tender and flaky texture in the final product. This action contributes to baked goods like pastries and biscuits, where a lighter and less chewy texture is desired. The term "waterproof" suggests that the gluten strands are restricted in their ability to absorb moisture, allowing for a unique structure that enhances the overall quality of the baked item.

Understanding this process is crucial in food technology because it highlights the importance of fat in texture and quality. Other options can be related to different cooking processes or effects but do not accurately describe the melting of fat and its interaction with gluten during shortening.
