Two alternatives: 1. Design a machine that uses air streams to eventually dehydrate the outer faces of the bread, then shoots puffs of pre-fabbed soot/butter mix on the result. Bonus: market for add-on soot/butter packs. 2. Design a machine that is by default always on fire, which will temporarily reduce the heat to a glowing red when you hit a button to make toast. That way failures merely return the device back to its original burning state (albeit with a temporary burnt toast smell).
