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
Yeah, certainly there are many different kinds of bread. I’m sure I was overly broad in designating all dough made with butter as pastry. I was responding to the previous comment , which I interpreted as implying that butter(or bonemeal, in a pinch) is a necessary ingredient in bread.
