About
Idli are small, pale, spongy cakes steamed from a batter of parboiled rice and urad dal, soaked separately, ground and left overnight until it doubles. Sambar is the stew they are eaten with: toor dal cooked to a mush and simmered with tamarind, vegetables and a spice powder of roasted coriander, chilli and fenugreek, then finished with mustard seeds, curry leaves and asafoetida fried in oil. Idli moulds are cheap in Indian shops, but you do not need one. Small heatproof bowls, ramekins or a cloth-lined steamer basket in a lidded pot make good idli. The ferment matters far more than the shape.

Steps
Step 1
Rinse the rice and soak it in plenty of water for 4 to 6 hours. In a separate bowl, rinse and soak the urad dal with the fenugreek seeds for the same time.
5 min
Step 2
Drain the dal and blend it with about 150 ml of the iced water in short bursts for 5 to 8 minutes, until very smooth, pale and fluffy; a drop should float in a glass of water. Scrape it into a large bowl. Blend the drained rice with about 200 ml water to a fine paste with a slight grit, like wet semolina. Add it to the dal with the salt and mix by hand for a minute.
20 min
Tip: Mixing by hand is not superstition. It warms the batter slightly and spreads the yeasts evenly.
Step 3
Cover the bowl loosely and leave it somewhere warm, ideally 26 to 32°C, for 8 to 14 hours, until the batter has roughly doubled, looks bubbly and smells pleasantly sour. In a cold kitchen, put it in the oven with only the light on.
5 min
Tip: Leave room in the bowl. A good batter can climb over the edge overnight.
Step 4
For the sambar, simmer the toor dal with the turmeric and 500 ml water, partly covered, for 40 to 50 minutes, or about 10 minutes in a pressure cooker, until it collapses completely; add a splash of hot water if it thickens before the dal is soft, then whisk it smooth. Meanwhile toast the dried chillies, fenugreek and cumin in a dry pan for 1 to 2 minutes, until the fenugreek turns light brown, add the ground coriander for the last 30 seconds, then cool and grind to a powder.
50 min
Step 5
In a saucepan, simmer the shallots, carrot, eggplant and tomato in the tamarind water and 300 ml water with the salt and jaggery for 10 to 12 minutes until tender. Stir in the sambar powder for 3 minutes, then the dal, and simmer 5 minutes more to the thickness of a hearty soup.
20 min
Step 6
To steam the idli, grease idli plates, small heatproof bowls or ramekins with oil. Stir the batter gently once and fill each two-thirds full. Set them on a rack or trivet over 3 to 4 cm of boiling water in a wide pot, cover and steam on medium-high for 10 to 12 minutes, or 15 for deeper bowls, until a skewer comes out clean. Rest 5 minutes and loosen with a wet spoon.
20 min
Tip: No mould and no bowls: line a steamer basket with damp muslin, pour in 1.5 cm of batter, steam 15 minutes and cut into squares.
Step 7
Heat the oil in a small pan, add the mustard seeds and let them pop, then the dried chillies, curry leaves and asafoetida for 10 seconds. Pour the tempering over the sambar and add the coriander. Serve the idli hot with sambar poured over or in a bowl on the side, with coconut chutney.
3 min
Watch: Curry leaves spit hard in hot oil. Stand back as they go in.

Substitutions
Parboiled rice → Idli rava (coarse rice semolina)
Rinse 300 g idli rava, soak 30 minutes, squeeze it out and mix it with the ground dal instead of grinding rice. Common in diaspora kitchens.
Toor dal → Masoor dal (red lentils)
Cooks in 15 minutes and goes smooth easily. The sambar is a little thinner and less nutty.
Tips
- Batter that has not risen after 14 hours is usually too cold, not dead. Move it somewhere warmer and give it a few more hours.
- Leftover batter keeps four days in the fridge and gets sourer. Use it for dosa or uttapam.
- Sambar thickens as it stands. Loosen it with hot water before serving.
History & culture
Idli and sambar is breakfast across Tamil Nadu and the rest of South India, eaten at home, at railway stations and in the standing cafés of Bengaluru, usually with coconut chutney and filter coffee. It is also what people are given when they are ill, and travel food, packed in banana leaf for long train journeys because it keeps.
Steamed cakes are old in South India. Kannada and Sanskrit texts from around the 10th to 12th centuries describe iddalige and iddarika, though those early versions may not have been fermented or made with rice. Some food historians argue the method came from Indonesia; that is debated. The story goes that sambar itself was first cooked in the 17th-century Maratha court kitchens at Thanjavur.
Traditional — Tamil homes grind idli batter in a wet grinder, a stone drum that keeps the batter cool and fluffy. A blender works if you grind the dal in short bursts with iced water so it does not heat up. Idli plates are the standard mould; bowls and ramekins give slightly taller, denser idli. Asafoetida is marked optional only because most brands contain wheat flour.
