Why is sourdough bread shaped like a big rock which causes each slice to be a different size?
(self.nostupidquestions)
This community is for people to ask questions they feel stupid for not knowing the answer or how to find the answer. "How do I not already know this?"
It's not sourdough specifically that's baked that way. The large round loaves are called boules. Dough is typically shaped into balls, and it's easiest to leave it in ball form or baking it in a common round dish, vs specifically using bread pans.
It's also not traditional which is a selling point when people are looking for "artisanal" loaves.
I don't believe it really has any other advantage or disadvantages.
You can absolutely buy sourdough loaves.
Edit: crust. That's the only advantage. Boules develop a fantastic crust throughout the entire thing.
