February 20 Baking Stone vs Aluminum pan

Been attempting an original recipe for Vietnamese baguettes.  One of the “Perfect Sourdough” FB members shared a high hydration high protein recipe and I converted it to sourdough and used 5% brown rice flour to hopefully yield a crisper crust. 

The member also noted that she did not have a baking stone, but baked on an aluminum sheet pan.  I did a comparison bake for her, keeping everything thing else constant. 

With a higher thermal mass and better heat transfer, the baking stone produced an almost 50% increase in volume and a more open crumb structure.
