Nice find there, GOTG - many thanks for sharing.
I love looking behind the scenes in BIRs, as you always come across new delights (I like the ingeniuous use of washing-up bowls to contain the pre-cooked meats in this kitchen. There's practical thinking for you!).
As always with these kitchen clips it made for interesting viewing (good to see a healthy amount of stock being spooned in from the pre-cooked chicken bowl. Something I like to do myself, but not all BIR chefs do this.)
The vindaloo looks good, but I've only had time to take a quick look at it, and was puzzled by a couple of things. First, apart from the addition of what he calls a 'naga' paste (which for some reason he attributes to the use of North African chillies), I didn't see any spices being added (unless they were in the chilli paste?). I may have missed it though, so will go back and have a closer look later.
And there are another 20 vids to check out, too.
Splendid.
