It takes longer too toast bread that has less sugar content, so with no-knead, I let it go with my normal setting, then re-start it when that's done so I can get more color.
Someone here said that he/she felt that toast in the BSO was more like baked than toasted.
After giving it some thought, I actually agree. I think it's because the elements are located so far from the center rack.
Still, it's very convenient and not really all that much different than in a toaster.
