This Kushboo Idli recipe (also known as Mallige Idli or Sponge Idli) makes the iconic super-white, soft and fluffy idlis famous across Tamil Nadu and Karnataka. If you have been wondering how to get that hotel-style “jasmine” texture at home without using soda or castor seeds, sago (javvarisi) is the secret ingredient used in Kushboo idli batter.

I first tasted these super-white, “plumpy” Kushboo Idli —popularly known as Mallige Idli or Sponge Idli here in Bangalore – at my own marriage feast. For over a year, I tried every combination to recreate that iconic texture, but friends insisted it was a “secret” recipe only for professionals!
The secret, it turns out is Sago (Javvarisi) and Castor seeds. While I’ve experimented with castor seeds before, this perfected version is inspired by a post from Priya’s Feast. It uses sago to achieve that incredible fluff without needing castor seeds or baking soda.
I even tested this in a mixie using ice water, and the results were surprisingly soft—though a grinder will give you that “perfect” hotel finish. To get them truly spongy, don’t skip using a cotton cloth (thuni) for steaming!
I’ve recently updated this post with new photos and a video to help you master these at home. No more “secret” ingredients—just proper fermentation and these simple steps. I’m sure you’ll be happy with the results!

What is Kushboo Idli?
Named after the popular South Indian actress, these idlis are distinct from regular idlis. They are remarkably white, plumpy and have a melt-in-the-mouth texture. While some traditional versions use castor seeds (aamanakku vidhai), this recipe uses Sago (Javvarisi) to achieve that same sponginess safely and easily.
Why this recipe works:
- The Sago Secret: Sago acts as a natural softener and helps the batter trap more air during fermentation.
- No Castor Seeds: Safe for everyone, avoiding the potential digestive sensitivities associated with castor seeds.
- Mixie-Friendly: Detailed tips on how to get grinder-quality results using a regular mixer grinder.
Ingredients for Spongy Kushboo Idli
- Idli Rice (Parboiled Rice): 2 Cups (Use high-quality Salem rice for the best whiteness).
- Urad Dal (Whole White Gram): ½ Cup.
- Sago / Javvarisi (Sabudana): ¼ Cup (Use the opaque white variety, not the nylon/transparent one).
- Salt: As needed.
- Ice Cold Water: For grinding (essential if using a mixie).
💡 Pro-Tips for the Best Results
- Washing the Rice: Wash the idli rice at least 3-4 times until the water runs clear. This is the secret to achieving that brilliant white color.
- Temperature Control: When grinding in a mixie, the blades heat up, which can “cook” the Urad dal and prevent it from fluffing up. Always use ice-cold water to keep the batter cool.
- The “Thuni” Method: For the softest texture, always use a wet cotton cloth over your idli plates instead of greasing them with oil. This allows the steam to circulate more evenly.
Step-by-Step Instructions
- Soaking: Soak the idli rice, urad dal, and sago separately for at least 4-5 hours.
- Grinding Urad Dal: Grind the urad dal first with sprinkles of ice water until it is thick, foamy and doubles in volume.
- Grinding Rice & Sago: Grind the rice and sago together until you reach a smooth, fine-grit consistency.
- Mixing: Combine both batters using your hands. The natural warmth of your hands helps initiate the fermentation process.
- Fermentation: Allow the batter to sit in a warm spot for 8–12 hours. In cooler climates or during monsoons, you may need up to 15 hours.
- Steaming: Steam on medium-high heat for 10 to 15 minutes. Let them rest for 2 minutes before demolding.
- Enjoy with your favorite chutney and sambar. I served it with tomato chutney.

Kushboo Idli Recipe
Ingredients
1 cup = 250ml or 200ml (use same cup to measure all ingredients)
- 2 cup Idli rice / Salem rice / parboiled rice
- ½ cup Urad dal
- ¼ cup Sago / Javvarisi / sabudana ( White big ones, not the crystal nylon variety )
- Salt and water as needed
Instructions
- Wash the idli rice thrice and soak in enough water. Washing the rice properly helps to give white colored idli. Wash the urad dal once and soak it. Wash the sago once and soak it. Soak everything separately for minimum 4 hours.
- Take a big sized mixie jar. You can grind in grinder too. Firstly grind the soaked urad dal to a smooth paste adding little ice water. Collect the batter in a big bowl. Next grind the soaked rice and sago together in 2 batches. Grind to a smooth batter adding sufficient ice water. Do not use more water.
- Mix urad dal batter and rice, sago batter using your hand. Cover and allow the batter to ferment overnight or minimum 15 hours based on the weather in your place.
- The next morning, batter would have raised well. Add required salt and mix well. Consistency of batter should be like our regular idli dosa batter. It should be thick and pourable.
- Now take an idli plate and spread a wet cloth over it. Pour ladleful of batter in each hole. Roll boil water in an idli pot. Place the idli plate over it. Cover and steam the idli for 10 minutes. Dip your forefinger in water and make a hole in one of the idli. If your finger comes out clean, idli is cooked. If your finger is sticky, cook for few more minutes. Switch off the flame and rest the idli inside the pot for few minutes.
- To remove the idli, take the idli plate and invert it over another empty plate. Sprinkle water over the wet cloth and remove the cloth gently. Idli comes out smooth and super soft. Enjoy with your favorite chutney or sambar!

Notes
- I have not used castor seeds or baking soda in this recipe. Both are completely optional.
- Do not make the batter too thick or too thin. So add water carefully while grinding the batter.
- If you live in cold place, do not add salt while grinding the batter because salt curbs the fermentation.
- Proper fermentation is important for this idli batter. So leave it for 8 to 15 hours based on the weather condition.
- Last but not the least, use a cloth to make these idli. It makes a big difference in texture and looks.

Frequently Asked Questions (FAQ)
1. Why are my Kushboo idlis hard?
This usually happens if the urad dal was not ground to a fluffy consistency or if the fermentation was insufficient. Ensure the batter has doubled in volume before steaming.
2. Can I use Poha instead of Sago?
While poha makes idlis soft, sago provides the specific “springy” and “plumpy” texture unique to the Kushboo variety. For the authentic version, sago / Big sized Javvarisi is recommended. You can use Nylon Javvarisi as well but the quantity should be more. Please check the comments section to read the feedback about it.
3. How do I get that pure white color?
Use premium idli rice and wash it thoroughly. Also, avoid adding too much water while grinding. A thick, aerated batter stays whiter.
4. Is this batter suitable for Dosa?
Yes! The addition of sago makes for very crispy, golden-brown dosas the next day.
What to Serve with Sponge Idli?
These idlis are like sponges and soak up sambar and chutneys beautifully. Pair them with

wow.. i was looking for this recipe only.. thank uuuuu :)
Hi Chitra as you said I am also trying this idli for longtime I tried the same ratio but didn't add backing soda but mine was very hard but not flat do you have any idea where I might wrong?
Hi manju , thanks for trying.Iam sorry ur idli turned hard. I dont know y but there are chances of getting hard due to some reasons. Did u use crystal sago , if so use white big ones.. The raw rice should be a good quality one..The consistency should also be right. Try adding little water if the batter is too thick and also add soda next time when u make. U'll get it rite for sure :) Hope this helps..
Bookmarked Chitra! i loved the onion chutney though I may reduce the garlic more. However the idli's. So you did not use the castor seeds here?
Yes shri , i dint use castor seeds but i used cooking soda :)

Note : pacharisi means the rice we are using for the dish pongal no .. that one?
