Roti (also known as chapati) is a flatbread native to the Indian subcontinent made from stoneground wholemeal flour, traditionally known as atta, and water that is combined into a dough. Roti is consumed in India, Pakistan, Nepal, Sri Lanka, Singapore, Maldives. It is also consumed in parts of Africa, Fiji, Mauritius and the Caribbean, particularly in Trinidad and Tobago, Jamaica, St Lucia, Guyana and Suriname. Its defining characteristic is that it is unleavened. South Asian naan bread, by contrast, is a yeast-leavened bread, as is kulcha.
