Recipes for unleavened bread occur in most cultures around the world. Roti, one choice for a tasty, unleavened Indian bread, is an interesting case because it can be a general term for bread or refer to the bread of a specific region.
The history of bread in India and surrounding environs can be traced back more than 3,000 years, and in that time, there's been a lot of roti (bread) experimentation. One way to sort out the confusion is to look for any words that occur before the term roti. They'll give you a hint about the specifics, usually the grains or special ingredients included in that bread. If all the recipe or label says is roti, you'll have to check the ingredient list to get a better idea of the ingredients involved.
With an ingredients list that can include chickpeas, coconut, onions, bananas or any of a cornucopia of different ingredients, this bread is the curious cook's dream.
