Why is yeast added to bread dough and the covered with a cloth set aside few hours after baking?

It seems like you're mixing up two different steps in the bread-making process! Here's a breakdown:

1. Yeast is added to bread dough for a reason:

* Fermentation: Yeast is a living organism that feeds on sugar and produces carbon dioxide and alcohol as byproducts. The carbon dioxide gets trapped in the dough, causing it to rise and create the characteristic texture of bread.

* Flavor: Yeast also contributes to the unique flavor of bread.

2. Covering the dough with a cloth after baking is not common practice:

* Cooling: After baking, bread is usually allowed to cool on a wire rack to prevent condensation and sogginess.

* Cloth use: A cloth might be used during the rising stage, not after baking. This helps to keep the dough warm and moist, encouraging the yeast to work and the dough to rise properly.

To summarize:

* Yeast is added before baking to make the bread rise.

* A cloth is typically used to cover the dough during rising, not after baking.
