On March 10, 2026, Bangalore's dosas went dark.
Not because we ran out of batter.
Because we ran out of gas. Literally.
COMMERCIAL LPG SUSPENDED ยท HOTELS SHUTTING DOWN ยท HORMUZ CLOSED
The fix isn't more gas. It's less dependence on gas.
Electrify the kallu. Save the dosa.

The Problem: Our Dosas Run on Geopolitics
โฝ
The Supply Chain
India imports 62% of its LPG. 85-90% of that comes through the Strait of Hormuz. You know, the one that's currently closed because of a war.
๐
The Priority List
Govt's LPG priority: 1) Your home kitchen 2) Hospitals 3) Schools 4) Your favorite darshini. That's right โ restaurants are last in line.
๐ข
The Tragedy
Somewhere in Jayanagar, a perfectly fermented batter is crying. The kallu is cold. The dosa master is scrolling Instagram. This is not okay.
๐ The Numbers That Should Scare You

The Fix: Don't Replace the Kallu. Electrify It.
Here's the thing everyone gets wrong. They think switching to induction means throwing away the dosa master's beloved kallu โ the one that's been seasoned for 15 years, the one that makes that particular crisp, the one the cook has a personal relationship with.
No. Keep the kallu. Just change what's underneath.
A traditional dosa kallu (whether cast iron or mild steel) is already ferromagnetic โ meaning it's naturally induction-compatible. Nobody told you this because the entire supply chain is organized around gas. But the physics has been waiting patiently.
The Retrofit: "Dosa Charger"
Slide an induction coil module under the existing kallu. That's it. The cook's experience changes almost nothing. Same tawa. Same seasoning. Same spreading motion. Same height, same angle. The fire just becomes invisible.

How Induction Actually Works
No flame. No gas. Just physics. Here's the 30-second version:
1๐
Electricity โ Coil
AC current flows through a copper coil underneath your kallu. Creates an alternating magnetic field.
2๐งฒ
Magnetic Field โ Iron
The magnetic field hits your iron/steel kallu and creates tiny electric currents (eddy currents) directly in the metal.
3๐ฅ
Eddy Currents โ Heat
Those currents generate heat โ directly in the kallu itself. No flame. No wasted heat. The kallu IS the heating element.
Faraday figured this out in 1831. We're just finally using it for dosas.
Does It Work on Iron Kallu?
Iron and cast iron are THE BEST materials for induction. They have high magnetic permeability โ meaning the electromagnetic field couples with them more efficiently than almost any other metal. Your grandmother's cast iron kallu is literally the perfect induction cooking surface. The universe has been trying to tell us this.
Mild steel (which most commercial dosa kallus are made of)? Also ferromagnetic. Also perfect. The only material that doesn't work with induction is non-magnetic stainless steel (austenitic / 300 series). But nobody makes dosa kallus from that because the thermal properties are wrong anyway.

The Parts Exist. Somebody Just Needs To Put Them Together.
The components for an induction retrofit kit are commodity items. Chinese manufacturers sell SKD (Semi-Knocked-Down) kits with everything you need โ PCB board, IGBT power module, copper induction coil, temperature control. You can order 5 units minimum. Here are real links:
Note: These are component kits, not finished products. You'll need an enclosure, wiring, and a qualified electrician. If you're a kitchen equipment manufacturer reading this โ this is your moment. The demand is literally on the front page of every newspaper today. Build the retrofit kit. Price it at โน40-70K. Sell a million of them.

Somebody Get Danish Sait To Make This Video
This crisis needs the only man who can make Bangalore laugh and cry at the same time. Here's the script. Danish, if you're reading this, this is your public service announcement. Do it for the dosa.
INT. DARSHINI โ MORNING. The kallu is cold. The batter is ready. Danish enters as "SHANKAR" โ a darshini owner in a lungi, staring at his phone.
SHANKAR: (to camera, deadpan) "See this? This is CNN. There is one fellow โ sitting in Iran โ who has closed one road in the sea. Because of that, my gas cylinder is not coming. Because of THAT... (dramatic pause) ...Jayanagar 4th Block is not getting masala dosa."
He walks to the cold kallu and pats it sadly.
SHANKAR: "This kallu... my father's kallu... seasoned since 1987. It has seen three Prime Ministers, two recessions, and one time when I accidentally made a dosa shaped like Rajkumar's face. But today? It's cold. Cold like my mother-in-law's heart."
Cut to: a customer enters, hopeful.
CUSTOMER: "Anna, one masala dosa." SHANKAR: (long pause) "...We have bread. And sadness." CUSTOMER: "What?" SHANKAR: "The Strait of Hormuz is closed, sir." CUSTOMER: "What is Hormuz? Is that a new restaurant?"
Shankar pulls out a phone, shows the customer a map.
SHANKAR: "See this? This little gap between Iran and Oman? My gas cylinder has to come through THIS. 7,000 kilometers on a ship, through a war zone, to make your โน60 masala dosa. (beat) Meanwhile, BESCOM electricity is coming from... (points vaguely) ...Ramanagara. 50 km. On a wire. No ship. No war. No Hormuz."
Cut to: Shankar showing an induction coil module to camera.
SHANKAR: "See this? This goes UNDER the kallu. Same kallu. Same seasoning. My father's ghost will not be angry. But now, instead of waiting for a gas cylinder that is stuck somewhere near Yemen... I plug this into the wall. (mimics plugging in) Bssssst. Done. Dosa time."
Final shot: Shankar making a perfect dosa on the electrified kallu. Golden. Crispy. He looks at camera.
SHANKAR: "They can close the Strait of Hormuz. They can close the gas supply. They can even close that annoying Zomato notification. But they CANNOT close my dosa. (flips dosa perfectly) #SaveDosa."
End card: #SaveDosa โ Electrify the Kallu.
Danish, we're not kidding. The dosa needs you. DM is open. Or just steal this script. We don't care. Just #SaveDosa.

What We're Asking
This isn't a startup pitch. This isn't a product launch. Nobody here is selling anything. This is a bunch of people who want their morning dosa and are tired of it depending on the geopolitical stability of the Persian Gulf.
๐ง
Kitchen Equipment Makers
You already make dosa bhattis. Now make an induction retrofit module. The components are on Alibaba. The demand is on Page 1 of today's newspaper. Just do it.
๐ณ
Restaurant Owners
Next time your equipment supplier visits, ask: "Do you have an induction retrofit for my kallu?" If enough of you ask, they'll build it. Demand creates supply.
๐ฃ๏ธ
Everybody Else
Share this. Tag your favorite darshini. Tag Danish Sait. Tag the Minister of Petroleum. Use #SaveDosa. Make noise. Dosas are too important to depend on a strait.
