I have never seen it first hand, but I have been told some restaurants add a sprinkling of garlic powder to many of their curries.
It is a last moment addition prior to putting the lid on the carton
One "chef" who told me this was the author of the "secrets" ebook
I corresponded by emailed, about ten times, trying to get better results
He also mentioned adding ground coriander ,near the end of cooking a curry, too
I have now seen that done so it makes me think that, somewhere along the line, was a genuine source of information.
By the way, that's a great photo of the base!
Excellent
