Wheat Flour
All-purpose or plain flour is a blended wheat flour with a protein content lower than bread flour, ranging between 9% and 12%. Depending on brand or the region where it is purchased it may be composed of all hard or soft wheats, but is usually a blend of the two, and can range from low protein content to moderately high. It is marketed as an inexpensive alternative to bakers' flours which is acceptable for most household baking needs.
