An easy type of bread flour to use in bread machines is unbleached all-purpose flour with a high protein and gluten content. Generally, cooks should select bread flour according to the desired height and texture. Whole grain flours are an alternative choice to lighter all-purpose flours.
All-purpose flour that contains a lot of gluten is ideal for making a variety of bread recipes in a bread machine, which creates high-rising breads. This type of flour is not a good fit for denser breads that have a heavier texture. Cooks can also mix all-purpose and whole-grain flours to achieve an in-between texture.
