Forgive me for saying but isn't this what we re all trying to do though, perfect BIR dishes at home? I can't help but think of the many topics we have all read and discussed regarding regional variations, differing restaurants and their recipes, methods etc.
But I understand what your saying. It's like going full circle and finding yourself at the beginning again but not necessarily having moved forward. I sometimes find that covering old foot steps often reveals small details that I have forgotten or missed out. Perhaps this is what you need to.
I made a Karahi chicken last night spurred by Samsons recipe but I changed it to use spice mix and base. The result was by far the best Karahi chicken I have ever cooked at home. Even the wife commented on how nice it was. Not 100% perfect but the closest so far for me.
If the KD1 recipes are more to your preference, then perhaps you could apply what you know to changing them to suit what you think is more likely to be BIR. My only thought on this is that you'll likely end up at the beginning yet again.
For me, the only real way i'll ever produce the perfect BIR dishes is if the IG let me back into the kitchen to learn every single process. Pre-cooks, Pastes, Puree, Base, Ingredients, Methods, Recipes, etc. I don't feel i'll be able to accomplish this by using one recipe here and another method from there etc.
Currently, I am happy with the flavours I can achieve at home and I am happy to pay a visit to my local BIR if I crave the authentic BIR experience.
