Idlis hold a special place in South Indian cuisine. Just the mention of these small, round, spongy rice cakes can tempt any Indian — no matter how full they are. That is the magic of idlis.
The unforgettable flavor, and soft, spongy texture lingers on the palate, leaving idli lovers of all ages savoring the simple fare. For South Indians, it is a common breakfast dish, but this nutritious staple is welcome at any meal.
The origins of idli

The history of idli dates back over a thousand years. One might assume that idlis originated in India, but that is not necessarily the case.
Chinese Buddhist monk, Xuan Zang, noted in the 7th century that Indians lacked the knowledge and equipment for steaming food. Some food historians suggest that the steaming technique was introduced through trade and cultural interactions with Southeast Asia or Indonesia.
Between the 7th and 12th centuries, Hindu kings who ruled parts of Indonesia often traveled to India, accompanied by their chefs. These chefs are believed to have brought along the Indonesian dish Kedlis, which likely influenced the modern preparation method of idlis.

While considered an exotic dish in most countries, idli has become popular around the world — partly due to its unique texture and flavor achieved through fermentation; partly for its excellent nutritional profile that happens to be gluten-free and low in calories and fat; and partly because it is easy and inexpensive to prepare.
How to prepare idli
Idli is made from rice, lentils (urad dal) and water. The batter is allowed to ferment (rise naturally), which yields the sponge-like texture. To achieve the right batter consistency, you need a precise ratio of rice to urad dal.
Ingredients:
- Rice – 4 cups
- Urad dal – 1 cup
- Fenugreek seeds – 1 teaspoon (optional)
- Water – as needed
- Salt – to taste

Instructions:
1. Soak the ingredients – Soak the rice and lentils in water separately for about 6 hours. Fenugreek seeds can be soaked with the lentils to help fermentation
2. Make the batter – Drain the lentils and grind to a smooth paste with a little water. Then drain the rice and grind to a slightly-more-coarse paste. Mix them together in a bowl.
3. Ferment the batter – Cover the bowl with a clean towel and allow the batter to ferment overnight (or 8–12 hours), during which it will rise and become fluffy.
4. Steam the idlis – Pour the fermented batter into idli molds and steam them for 10–15 minutes. When ready, the idlis will have a spongy texture.
