Why Does Steam Help Some Bread Crusts?
Steam helps some bread crusts because it keeps the outside flexible while the loaf expands! Later, the steam dries away and the crust turns into a crisp, shiny shell. Bakery ovens add steam on purpose.
More fun facts
- Some bakers pour a little water into a hot tray in the oven to make steam, which helps bread get a crisp, shiny crust.
- Steam keeps the crust soft a little longer, so the loaf has more time to rise in the oven.
- Bread bakers may push a button that sends steam into the oven or spray loaves with a water mister.
- Steam only helps early in baking, before the crust has set.
- Steam is often used for rustic country breads baked on a hearth.
