What is the purpose of adding salt to pasta dough?

Adding salt to pasta dough serves multiple important functions that are essential in the pasta-making process. Primarily, salt is a key seasoning that enhances the overall flavor of the pasta. When added to the dough, it penetrates the structure and elevates the taste of the final product, making each bite more enjoyable.

Additionally, salt plays a role in strengthening the proteins in the flour, particularly gluten. This strengthening contributes to the pasta's structure and elasticity, allowing it to hold its shape during cooking. A well-seasoned dough will lead to a pasta that has a better bite and texture, crucial for achieving a desirable culinary experience.

While salt does not directly affect the cooking time or significantly alter the color of the pasta, it is an essential ingredient for both flavor and texture. Therefore, the correct answer highlights the importance of seasoning and the strengthening effect of salt on the dough.
