Oh, I never actually bake in the machine. I just use 'em to do the grunt work, then I pan the dough and bake it conventionally.
ETA: I should probably expand on that. I've found in the past that bread baked in the machine was unsatisfactory, and haven't done it in years. Instead I make a single batch of dough in my conventional machine, a double batch in the horizontal machine, and combine them. With the recipe I use for my daily sandwich bread, that yields five small 1-lb. loaves.
I've not used a Zojirushi before, nor has anyone I know, so I'll probably make the experiment of baking in the Zo by way of a compare and contrast.
