Nice detailed Post CH and sorry you didn't get a good result. I think the same thing has happened to me whereby adding more (oily) base and reducing just made the curry oilier but without the body of the sauce forming. I mean I like an oily curry but there is a limit.
Since the whole Fleet 5 episode I've re-evaluated my position on making curries, changed my kit from wok and spatula to ally pan and chef spoon and I've had a few disasters and lost my curry mojo along the way
In particular my consistency has weakened.
Over the weekend I used the last of CA's simple base and started a simple vegetable curry with a few tablespoons of virgin coconut oil. The result was unexpectedly delicious and my wife and I were purring away as we ate it.
Nobody said this would be easy

BTW I see the funny characters in your last post as well as Dalpuri.
