I’m not even sure what ground up bones would do for bread. Is calcium a binding agent or something?
I looked it up because i also always wondered. Turns out bone marrow can replace the butter used to make bread
But… you don’t use butter to make bread. Flour and water, maybe some yeast. If you’re using butter to make dough, then it’s some kind of pastry.
you need fat to make toast bread, what a lot of americans and people in the west default to imagining when you say “bread”.
the fat prevents longer gluten chains from forming, which makes the bread light and airy, compared to traditional “proper” bread which tends to be denser and chewier and oh no now i’m hankering for levain
