Mondo Knows Facts

Scoring a loaf controls where it bursts

A deliberate cut gives expanding steam and gas somewhere to go

Oven spring pushes a loaf upward as trapped carbon dioxide and steam expand. Without a cut, the crust sets before the middle finishes rising and the loaf tears at its weakest point. A slash through the surface chooses the weak point, so the bread opens along the line the baker drew rather than wherever it happens to split.
