Pain de mie
Pain de mie is a white or brown bread with a thin, soft crust. It is mostly sold sliced and packaged in France. Pain is the French word for "bread", and la mie is the soft part of bread, called the crumb in English. Pain de mie is most similar to a pullman loaf, or to regular sandwich bread. Pain de mie usually has sugar in it,[citation needed] which makes it sweeter than most French breads. This bread is usually used for making sandwiches, or for toasting. It can be baked in a sealed pan, which prevents crust from forming. If not baked in a sealed pan, the crust can be cut off . Pain de mie is sold in rounded or rectangular shapes.
