I am curious, how do these chefs manage to get their frying pans in flames?
Water content from the garlic & ginger paste etc. mixes with the oil in the pan and spits out over the pan where the gas flame then ignites the oil to give the flambe.
Malc is on the money

Extremely simple to flame your Ally pan on your domestic burner.
1. Turn your gas on high
2. Put your Ally pan on the ring for a few minutes, until its extremely hot.
3. Add a Chefs spoon of oil, it will heat very quickly, you will see it shimmer and ripple and you will know its hot enough.
4. Pull the pan towards you, slightly off the rings centre, lift and tip the pan, so the oil has pooled furthest away from you.
5. Now add any water based substance to the pan and WHOOSH, FIRE, 2 feet high at least.
6. Warning, Don't do this, when you have a camera overhead.
7.
Disclaimer. Do this at your own risk. Stand well back and don't drop or leave go of the pan or serious burns may follow.
I was demonstrating this to fellow curry fans one day and I didn't want to have to clean the mess and pan after,
so I just gave the pan/oil a squirt of Lemon Dressing.WHOOSH, everybody run.
