Dosa Period BOrigin theory CVerified

Dosa is a South Indian dish. Rice and urad dal are ground with water on a stone mill, the batter is left overnight to ferment on its own, and it is then spread thin like a crepe on a hot iron griddle (tawa). Rice is the main ingredient; urad dal plays the supporting role, carrying the fermentation that gives the batter its sourness and lift. Both are long-established crops of South Indian soil. Dosa was made in home and temple kitchens, and later spread to become the signature dish of the city tiffin houses, the cafés that serve light meals and snacks.

According to the food historian K. T. Achaya, the tosai (dosai) first appears in writing in Tamil Sangam literature of about the 6th century, when it was perhaps made from rice alone and cooked in a pan with a little oil. The Mānasollāsa (c. 1130), a 12th-century Sanskrit encyclopedia compiled by the Chalukya king Someshvara III, then sets out how to make a dosaka. A batter of split Bengal gram (chickpea) is cooked in an oiled pan, and the text adds that urad dal and other pulses can be prepared the same way. Rice is not named. Achaya likewise reads this dosaka as apparently made without rice. As the first account that describes how the dish was made, this 12th-century entry serves as one reference point. Its ingredients, though, differ from today's method of fermenting a rice and urad dal batter overnight, and the sources do not show where the dosa as we know it begins. The word itself has deep roots: tōcai/dosai goes back to the Dravidian tōy (to ferment, to soak), and the Kannada dōse and the Tulu doṣe come from the same source. The fermented batter at the heart of the dish is written into the languages of the region.

The masala dosa, folded around a filling, is a separate and much newer dish. Its sautéed potato filling could only come into being after the potato had crossed the ocean from South America and reached India.

Two claims the sources do not support have long clung to the dosa.

The first concerns its earliest record. Achaya is sometimes quoted as saying that dosa is first mentioned in 8th-century Tamil literature, but that statement cannot be found in his Indian Food: A Historical Companion (1994). The first record Achaya himself names is Tamil Sangam literature of about the 6th century. Even so, the first point at which a name appears in writing is not the same as the moment a dish was actually born.

The second ties the stuffed masala dosa to the 12th-century Chalukya court: a cook of Someshvara III is said to have wrapped leftover curry in a dosa, and so the dish began. But the potato inside the masala is a South American crop, and the year it reached India is not known. George Watt's A Dictionary of the Economic Products of India (1893), a survey of the country's products, places its arrival somewhere between the end of the 16th and the beginning of the 18th century. A potato-filled dosa could not have been served at a 12th-century court. Achaya, too, writes that the potato stuffing belongs to modern times. The actual masala dosa is a modern offshoot, said to have been popularized in 1930s Madras by K. Krishna Rao of the Udupi restaurant tradition. The thin dosa itself reaches back to the medieval period; the potato-filled masala dosa is a modern creation.

Set these stories aside and one unsettled question is left: did the dosa begin in Tamil country or in Karnataka (Udupi)? Achaya points to the Tamil region and finds the first record in Sangam literature. The food historian P. Thankappan Nair argues for Udupi, and on the Karnataka side there is the dosaka of the Manasollasa. Each claim rests on its own independent written record, and because they point to different regions, they do not converge on a single answer. Which region is the dosa's true home remains undecided.
