Oh, and because wide bread is now "artisanal", long-slot toasters have acquired luxury pricing and are more expensive than four-slot toasters. Even though they have identical heating elements.
I still think white bread makes a better grilled cheese, pb&j, and brioche makes superior french toast. Those are all terrible on multi grain bread, which has its own uses.
"When you want to bake as much bread as possible, you need robotic assistance. You have to get out of the way. If you have 12 or 15 oven decks, you can't physically load it fast enough."
