Chewy, great video and the curry looks lush
You mention 'singeing' in your post but I don't see any 'singeing' in the video.It's only since the visit to Zaal by some of the guys that has brought about the importance of this 'singeing' and you did mention it some time ago but you don't seem to be cooking hot enough to create the 'singeing' what do you think Chewy ? I am only trying to establish when this 'singeing' takes place 
Hi emiin-j
There's definitely a flame underneath that pan emin-j,
Just a simple domestic gas hob on high. Cooking BIR at home.
The singeing all happens between 1.00min - 2.00min
So you've got -
1. Hot Veg oil
3. Ginger Garlic paste.
3. Tomato Puree Dilute
4. Mixed Powder
5. Chilli Powder
6. A splash of lemon juice,
7. A dash of Worcestershire sauce
8 A pinch of salt.
All added in quick succession, singeing and sizzling as you create the Tarka. (Turn the sound up ;D)
Don't quite understand how your not grasping this my friend, as it's a good example of the technique.
You may remember when i joined cR0 back in Jan 2011,
I posted this Restaurant technique in a pdf, that I had created for friends.
It was well received by you and other members at the time.
