Why should dough be during the final proving?

There are a few reasons why dough should be covered during the final proving:

* To prevent the dough from drying out. The dough is at its most delicate state during the final proving, and it can easily dry out if it is not covered. This is especially important in dry climates or in homes with low humidity. Covering the dough will help to create a humid environment that will prevent it from drying out.

* To prevent the dough from forming a skin. A skin is a thin, tough layer that can form on the surface of the dough if it is not covered. This skin can make it difficult for the dough to rise properly, and it can also affect the texture of the finished bread. Covering the dough will help to prevent a skin from forming.

* To protect the dough from contaminants. Covering the dough will help to protect it from contaminants such as dust, insects, and pet hair. These contaminants can affect the taste and quality of the bread, so it is important to keep the dough covered during the final proving.
