This curry made me happy. It sure wasn't worse than some of the bad takeaways I experienced in UK.
Things that I believe may have contributed to its success in terms of flavour/smell:
* Chicken marinated using yogurt, garam masala, lemon and g&g.
* Spiced/Filtered oil
* Tomato puree from tins instead of tube
* Use of Kashmiri Mirch, which seems to improve the flavour overall.
* Slight changes in technique/method
I also finally cracked my favorite coconut rice recipe and added some grated ginger throughout
