Now, let's get into the science-y stuff! Yeast fermentation is the process that makes the dough rise, and it's like a tiny little miracle happening right before your eyes. As the yeast eats the sugars in the dough, it produces carbon dioxide, which gets trapped in the dough, making it rise like a balloon.
But, here's the thing: overproofing can be a real problem, and it's like the dough is saying, "Hey, I'm tired of rising, I'm just going to collapse now!" So, you need to keep an eye on the dough and make sure it's not overproofing, or you'll end up with a dense, flat loaf.
On the other hand, underproofing can also be an issue, and it's like the dough is saying, "Hey, I'm not done rising yet, give me more time!" So, you need to find that perfect balance, like Goldilocks, and make sure the dough is just right.
