Atta flour

Atta (Hindi , Urdu ) or Chakki Atta is a wholemeal wheat flour, originating from the Indian subcontinent, used to make flatbreads such as chapati, roti, naan, paratha and puri. It is the most widespread flour in the Indian subcontinent.
Properties.
Hard wheat, used to make atta, has high gluten content which provides elasticity, so dough made out of atta flour is strong and can be rolled into thin sheets.
Atta was traditionally ground in the home on a stone chakki mill. This is useful when using a tandoor, where the flatbread is stuck to the inside of the oven, and also makes chapatis softer as the dough absorbs more water.
