I've made a small variation of this recipe along with Blade's (where I used balti paste instead of tandoori). The lasan came up as the clear winner (although I didn't make them to compare, it's just that I was not really happy with any of the previous recipes I tried, which didn't remind me of my TAs at all -- although they were good); I didn't use black salt or white pepper as I couldn't source black salt and forgot to buy white pepper. The results seem more similar to that I used to get when ordering.
For this recipe, I used PC's tandoori masala, which seems to be one of the few PC masalas worth writing down.
