I'm with billycat on this one Panpot. I'm not disputing that you are just reporting what you have been shown but, whatever that recipe is, it ain't a Rogan Josh!
The Ashoka so called 'rogan josh base' is far closer to a tandoori masala, containing as it does large amounts of cream, almond powder, and creamed coconut. You even call it a masala in some of the recipes.
Without meaning to piss you off, are you sure you (or they) haven't got your wires crossed somewhere along the way?
P.S. It does sound like a very tasty recipe though, just not RJ.
