I would like to purchase a baking stone. I am justifying this due to the abundant baking books I have and my desire for freshly baked bread. I am uncertain what type/brand would be sufficient for my needs. I have an electric oven, I don't know if this makes a difference or not. I do anticipate making pizza every now and again. But baking breads and other savory items are what I will be doing most of all. I appreciate any suggestions. Thanks!
