Chapati flour, or “atta,” is a type of flour used in India. It can also be called roti flour, because it is used for making rotis (Roti were called “chapati” by the British). Chapati flour is whole wheat flour with a finer grind than common whole wheat flour.
Chapati is made from common wheat and is high in gluten. Chapati flour is used for making many common Indian flatbreads, like parathas, rotis and puris.
