Oh I'm sure you'll present the questions in the delicate, discrete and palletable manner that is your want

I think that the limited number of spices you mention would be about right for most of the main curries (plus fresh toms, etc)...e.g. bhuna, madras, vindaloo, jalfrezi, etc.
I expect he uses some whole spices (though and mixes of spices) for things like rice.
I expect he also uses a tandoori masala (maybe a commercial powder or paste) for CTM, etc
I'd be pretty sure he uses a cream/evap/coconut/almond paste (of come concoction) for korma and CTM
I'd be pretty sure he uses other commercial pastes (and possibly masalas) too.
No fenugreek (dried leaves) suprises me a little (he'll surely use it if he makes baltis?)
STOCK is a big question mark for me!

OIL (source of) is another!

HEAT is another (I'm sure this creates "the magic" as with Chinese cooking)

If you only got answers to these questions I'd be happy

.....well...sort of.... :
