If you let (bread) dough rise, the recipe always asks to cover it. Years ago, I read to cover it with a wet towel. Nowadays, I see more and more recipes that ask for plastic wrap (aka saran or cling wrap).
The towel lets air through, the wrap does not. What is the difference between the two in the end result? What is best to use and why?
I'm taking about the first as well as the second (proofing) rise. If there is a difference between the phases, please inform me.
