I spent quite some time trying to crack naans. I'd say 50% of Chris's success here comes from the right ingedients, but to be honest, a lot of recipes are very similar in their ingredients. What cracked it for me was the method Chris uses. For me the missing key was the upside down pan, very quick cook, top and bottom. That's the key. Why can the take-aways somehow manage that naan flavour so easy? Because they have a tandoori oven and we don't! So we need to recreate our own, and we can do that by ensuring the naan sticks to our pan and then turning it over. Nothing else works quite the same, other than a tandoori oven of course.
