Maybe I’m too European for this, but I would never have thought of putting sugar in regular bread. Even milk buns don’t have added sugar in them, unless you count lactose.
…I’ll have to try this, because it sounds off to me. Like putting a dishwasher in the bathroom. Not really insane. But I’d quietly judge someone who does that.
Edit: Not great for bread.
It does.
Look up sourdough recipes. The bacteria and yeasts will eagerly eat some longer-chain carbs. They aren’t picky. Same goes for commercial supermarket yeasts.
