Malligai Poo Idli/Kushboo Idli – மல்லிகைப்பூ இட்லி /குஷ்பூ இட்லி
Soft as Jasmine, Famous as Kushboo!
Discover the secret to making ultra-soft, fluffy Kushboo Idli / Malligai Poo Idli—a South Indian steamed breakfast delight that's as white, pillowy, and irresistible as its namesake.
If you're searching for ultra-soft, fluffy white idlis that practically melt in your mouth, your quest ends here—with the iconic Kushboo Idli, fondly known in Tamil as மல்லிகைப்பூ இட்லி (Malliga Poo Idli). Named after the voluptuous charm of Tamil cinema’s superstar Kushboo, this idli isn’t just a dish—it’s a memory from the 90s, a soft steamed tribute to a cultural craze.
These idlis are cloud-soft, thanks to a secret touch of sago (javvarisi) and a dash of baking soda or traditional castor seeds (kottamuthu). Whether you’re in Malaysia, Madurai, or Mumbai, this South Indian classic will win over your breakfast table—every single time.
From Jasmine to Kushboo
From jasmine petals to silver screen softness—this idli got a celebrity makeover and the crowds followed.
This idli, once quietly known as Malligai Poo Idli for its snow-white fluffiness, was later rebranded, marketed, and glamorously served in many popular Tamil Nadu restaurants under the revived name—Kushboo Idli. All thanks to the soaring popularity of then-superstar Kushboo, whose fair skin, soft charm, and screen presence matched the pillowy perfection of these idlis - as voluptuous as her. The name stuck, the idlis soared, and every tiffin stall from Madurai to Mylapore had it proudly listed on the menu.
This soft and spongy Kushboo Idli recipe was first scribbled down during one of those cooking shows—specifically from a segment by Chef Damodar, who dropped a delightful twist into the batter: just two humble castor seeds (Kottamuthu) in place of the usual baking soda. According to him, this was the magic touch to make idlis rise like dream clouds—fluffy, round, and oh-so-perfect.!
And he wasn’t the only one. Even my ever-resourceful house help used to say with confidence,
“Kottamuthu pottaa idli pandhattam varum ma!”
(Translation: Add castor seeds, and your idlis will puff up like balls!)
She would pluck them with surgical precision from a neighbourhood tree and present them to me like rare heirlooms. But alas, here in Malaysia, Kottamuthu isn’t as easily available as my nostalgic heart desires. So for practical (and global) reasons, this version calls for a pinch of baking soda instead.
ProTip: If you’re living abroad and can’t get castor seeds, use baking soda. Your idlis will still steal the show.
And guess what? After years of chasing soft idlis with baking soda here in Malaysia, I finally sourced fresh Kottamuthu (Castor Seeds)—yes, the real deal! This time around, I’ve made Kushboo Idli the old-school way, just as Chef Damodar and my ever-wise house help taught me. And oh my—the fluff, the bounce, the aroma! It's not just a recipe now—it’s a sweet reunion with my food memories.
If you're lucky enough to get your hands on Kottamuthu, do try it once. It’s an old trick that still works like magic.
Did You Know?
Just in case you’re new to it—Castor Seeds = Amanakku Vithai, the same ones used for making Amanakku Ennai / Castor Oil / Vilakkennai. (And if you’re curious—or concerned—about the safety of using castor seeds in cooking, scroll down to the Food Safety Note. Don't worry, I’ve got you covered.)
The Kushboo Fever
Flashback to 1996—when Tamil Nadu went head over heels for Kushboo and restaurants began proudly serving Kushboo Idlis as a named item. Just when everyone was lining up outside hotels, I was laid up in a hospital bed thanks to a glorious viral fever. You know the scene—no appetite, the works: vomiting, diarrhoea, a doctor waving his finger and prescribing only steamed South Indian breakfast foods like idli or rice porridge.
And I? I swerved the kanji and clung to Kushboo Idlis like a woman possessed. No chutney, no sambar, nothing fancy—just sugar-dusted, steaming hot idlis thrice a day, every day, for an entire week. When Tamil Nadu had Kushboo fever, driving them to build a Temple for her, I had Kushboo Idli fever. Truly. That was the only food I could stomach, and ironically, the only one I craved.
Even my father-in-law, sweet soul that he was, knowing my love for Biryani promised me:
“Get well soon and I’ll take you to Angannan Biriyani.”

 |
Fluffy Kushboo Idli |
Ingredients for Kushboo Idli / Malligai Poo Idli
(Soft South Indian Idli with Sabudana & Urad Dal)
For Soaking & Grinding:
- 3 cups Idli Rice / Parboiled Rice
- 3/4 Cup Sabudana / Sago / Javvarisi
- 1 Cup Urad Dal / Ulutham Paruppu
- 2 Seeds Castor Seeds / Kottamuthu (optional – see Pro-tips below)
- Water – as needed for soaking & grinding
After Grinding:
- Salt – to taste
- Water – as required, to adjust batter consistency
Optional:
- A few drops of Gingelly/Coconut oil – for greasing idli moulds (if not using non-stick)
Substitute for Castor Seeds: A pinch of baking soda can be used instead.
Method - Step-by-Step Instructions
Grinding the Batter
Soaking
- Rinse and soak the sago in 1½ cups water. Do not discard this water after soaking.
- If using castor seeds, crack them gently and use only the white inner part. Soak along with the sago.
- Wash and soak idli rice and urad dal separately for 8–10 hours or overnight.
Grinding
First, grind the soaked sabudana (sago) along with the castor seeds (kottamuthu), if using, into a smooth, lump-free paste using the same soaking water.
- Grinding Time: Approx. 15–20 minutes.
- Once done, transfer the sabudana batter to a large mixing bowl and keep it aside.
Next, grind the urad dal, using ice-cold water added in intervals to prevent the batter from heating up. The batter should be light, fluffy, and airy.
- Wet grinder preferred for best results.
- When done, remove the urad dal batter and add it to the sabudana batter. Set aside.
Now grind the soaked idli rice with ¾ to 1 cup water into a fine, smooth paste—thinner than the urad batter, but not watery.
- Once done, transfer this rice batter to the same bowl.
Mix all three batters—sago, urad dal, and rice—together thoroughly with your clean hand for 2–3 minutes.
- This hand-mixing step is essential for better fermentation—it naturally activates wild yeast and enhances softness.
Add salt at this stage or after fermentation, depending on your local climate.
- In warmer areas, it’s best to add salt after fermentation to avoid sourness.
Fermentation
- Cover the bowl and allow the batter to ferment in a warm place for 8–10 hours or overnight.
ProTip: If your region is cold, pre-warm your oven slightly and leave the batter inside with the light on. Or wrap it in a towel!
Steaming Kushboo / Malliga Poo Idli
- Gently beat the fermented batter to release trapped air.
- If you skipped castor seeds, add a pinch of baking soda to the portion you’re using now (approx. 3 cups).
- Grease the Idli moulds with oil or ghee. Alternatively, you can line the moulds with muslin cloths.
- Boil water in an idli steamer or pressure cooker (without weight) for 10–12 minutes.
- Spoon a ladleful of Idli batter into each mould, filling them evenly.
- Carefully place the Idli moulds into the steamer and tightly cover them with the lid.
- Pour batter into the idli moulds and steam on high flame for 3 minutes, then low flame for 6–7 minutes or until a skewer inserted comes out clean.
Once done, immediately remove the idli trays from the steamer and spread them out on the counter.minutes. Sprinkle cold water lightly over the steamed idlis.
- Stops the cooking process immediately, preventing the idlis from becoming dry or overdone.
- When done
- Helps retain the soft, pillowy texture Kushboo Idlis are loved for.
- Makes removing easier without tearing the idlis.
This old-school trick from Tamil kitchens works like a magic everytime
- Let the idlis rest for 2–3 minutes, then remove the idli from the idli tray using a spoon dipped in cold water for a smooth release.

FAQ

- Only in minute quantities and never raw. See safety warning below.
Q: What makes Kushboo Idli so soft?

Tradition Talks
The story of idli, that soft and soothing South Indian staple, goes back centuries. Ancient texts like the Kannada Vaddaradhane (c. 920 CE) mention a dish called iddalige, and the 12th-century Sanskrit work Manasollasa refers to iddarika—both believed to be early forms of idli. Some even say that Indonesian fermented rice cakes like kedli might’ve inspired our beloved idli when cooks travelled and returned from Southeast Asia between 800–1200 CE.
Fast-forward to more recent times, and cooks in Tamil Nadu and Karnataka began transforming the humble idli into a soft-as-clouds creation. By adding sabudana (javvarisi), aval (poha), and even a pinch of baking soda, they crafted what was fondly called Mallige Idli in Karnataka and Malligai Poo Idli in Tamil Nadu—named so for its jasmine-white colour and delicate softness.
