Your curry looks good steve, mind you most do in my opinion, how they taste is another matter. What I've learned so far is that the base provides more than bulk to a curry. In no particular order I have produced "bir" tasting curries at home using base recipe's from; CA, KD1, Chewytikka, Ashoka,Kushi. Chefs will put their mark on a base, but they are usually very subtle. The real secret was the use of a base onion gravy, which was always going to be revealed. A Chinese ta owner I know told me how to make curry paste, saying that I would hardly ever make it. 3 times I've made it, I still buy curry there, when I know how to make it myself. I would say the real concern for the established owners/chefs is competitors not home cooks.
Cooking on high heat on a domestic gas cooker has cracked home bir for me after studying the cr0 Zaal reports & videos. It's purely down to the cooking technique which I'll agree isnt the stuff that gets Michelin inspectors excited. The aroma when the first ladle of gravy is added to oil/tomato paste /GG /spice mix/ will tell me whether the curry is a hit or miss, it fills the house with the smell of a restaurant, not like a microwave curry, which contains roughly the same ingredients. Its purely about removing the rawness, especially from the spice mix.
To create my fav restaurant's curries, I would have to get their recipe exactly, whether it needs to be bulked as a commercial kitchen I don't know.Otherwise I'd be cooking something different
Things the bir's don't want the public to see are probably rats, cross contamination, yogurt on the turn.
What smells a little to me is the amount of vegetable ghee buckets(yellow ones) i've seen in the kitchens, yet there isn't much about its use coming to light, for whatever reason. I suspect it may be used extensively in my neck of the woods rather than oil. I would also like to hear from anyone who has used oil from the catering sized drums for home cooking & noticed any difference?
