UB,
have watched the interesting parts again (footage mins: 13:12, 15:17, 15:24, 15:30).
I?m very sceptical about the extent of what?s shown being useful to us ? meaning they are clearly highlights "bits of a jig saw" and a lot is not shown which would be needed to be 100% sure of what?s happening.
it is a bit mix and match.. but the very first curry went like this - high heat, oil, fry onion , capsicum,
add chili powder - spice mix, fenugreek until dark brown (13:26) then added
tom puree and red masala back to high heat then added precooked lamb.
the next shot looks like they filmed a different curry.
the base looks a bit like saffron.
agree looks similar in viscosity but this looks more opaque, seems basic looks like just onions, pepper, fresh toms.. No spuds, carrots etc
