But in 2026, the popularity of idli is not just limited to a traditional food, but it is about its connection with the ancient wisdom, with healthy food recognized by todays modern science.
Lets know more about the history, health benefits, and the future of this fermented superfood.
Origins and History of idili:
The history of the idli is a fascinating mixture of ancient literature and culinary migration theories. While it is now the world famous South Indian breakfast, but its origins are a subject to debate since long among the food historians.
There are three primary theories regarding how the idli came to be:
- The Native Indian Theory (Ancient Roots)
The earliest written records of a dish similar to idli is found in ancient Indian literature, suggesting it has the roots in the Karnataka region of India.
* Vaddaradhane (920 AD): This Kannada text by Shivakotiacharya mentions a food Iddalige, which is described as a dish made from a black gram (urad dal) batter.
* Manasollasa (1130 AD): A Sanskrit encyclopedia written by King Someshvara III describes Iddarika, which was made using fine urad dal flour made small balls and spiced with pepper and cumin.
These early versions of idili were made only of fermented of folured urad dal. But, they lacked the two defining features of the modern idli including the addition of rice and the process of fermentation.
- The Indonesian Connection (The Migration Theory of Idili)
Popular food historian K. T. Achaya mentioned with his research that the modern idli, the fermented rice and lentil cake is actually originated in Indonesia.
As per the concept, between the 8th and 12th centuries, Hindu kings of the Shailendra, Isyana, and Sanjaya dynasties ruled few parts of Indonesia and frequently traveled to from Indonesia to India to find brides. Their royal cooks likely brought with them the technique of fermenting and steaming rice cakes.
Mr. Achaya identified an Indonesian dish called Kedli or Kedari as the likely having ancestor roots of Indian idili. He argued that since South Indian cuisine didn’t historically emphasize steaming, the method was an imported innovation that perfectly adapted with Indian ingredients.
- The Arab Trader Theory
Another theory, is supported by historian Lizzie Collingham, which suggests that Arab trade travelers to the South Indian coast introduced the dish.
As, Arab traders were very strict about prefering halal as per their traditional dietary laws. To avoid confusion with local spicy or non-halal foods, they began making simple, bland of steamed rice balls that they can eat with coconut paste.
Over centuries, these flattened rice cakes evolved into the fermented idli, which we eat today are the mix of local Tamil and Malayali cooking traditions.
Evolution of the Idli
* Era: 920 AD, Source: Vaddaradhane (Kannada), Name: Iddalige, Main Ingredients: Urad dal only (No rice and fermentation mentioned)
* Era: 1130 AD, Source: Manasollasa (Sanskrit), Name: Iddarika, Main Ingredients: Spiced urad dal balls
* Era: 1250 AD+, Source: Post-Chola Period, Name: Idli, Main Ingredients: Found Inclusion of rice and overnight fermentation process
* Era: 17th Century, Source: Maccapuranam (Tamil), Name: Itali, Main Ingredients: Modern fermented rice & lentil mixture
The idli we eat today is a culinary evolved form. While the concept of a lentil cake existed in India for over a thousands of years, the fermentation and steaming process was most likely perfected through cross-cultural exchanges with Southeast Asia or Arab traders, eventually being refined into its soft form by Tamil cooks during the late medieval period.

Today, the day serves as a platform for food historians to discuss the dish’s origins, with some tracing it back to Indonesia’s kedli and even deep discussing on the 10th-century Kannada literature and the existane of idili.
