Wheat atta is a whole wheat flour that's brown in color and made from the entire wheat kernel, including the bran, germ, and endosperm. It's a key ingredient in many Indian dishes, such as chapati, puri, phulka, tandoori roti, and parotta. Atta contains gluten, which helps with rolling chapatis, and has better nutritional characteristics than wheat flour, including higher protein, dietary fiber, vitamins, and minerals.
