Roti (also known as chapati) is a flat bread originating from the Indian subcontinent, made from stoneground wholemeal flour, traditionally known as atta, that originated and is consumed in India, Pakistan, Nepal, Sri Lanka, Singapore, Maldives, Malaysia and Bangladesh. It is also consumed in parts of South Africa, Fiji, Mauritius, the southern Caribbean, particularly in Trinidad and Tobago, Guyana, Suriname, Jamaica, and Grenada. Its defining characteristic is that it is unleavened. Indian naan bread, by contrast, is a yeast-leavened bread. A kulcha in Indian cuisine is a bread-like accompaniment, made of processed flour (maida) leavened with yeast.
