The Loafyrinth

Toast

There is a certain style of bread, baked in a broad circular shape, that has a spiral or concentric pattern (lines of flour maybe?) on top. I'm curious about the origin of the pattern.

Are you maybe thinking of loaves that proof in a basket or banneton made of cane? They will often produce the kind of pattern you are describing.

That could very easily be it, if the loaves are placed top-down in the banneton and then baked pattern-side-up. It certainly makes more sense than what I was imagining. ? I've never used a banneton before.
