Hi Phil
Looks like a good Madras variant and I'm sure it tasted good with Kashmiri and Deggi chilli included.
I prefer Kashmiri for it's great flavour, but I have used Deggi and it is quite similar heat wise and gives good colour, but not quite there for my taste.
Using Bassar Masala and Cumin would definitely lean it towards a Pakistani BIR flavour,
I would say most Bangladeshis wouldn't even know what Bassar Masala was!
It brought back memories of this small pakistani guy in his shop "The Spice Souk" in my town
and I used to buy his homemade Masala, which he called "Top 30",
being that it was his secret blend of 30 spices and it was simply amazing! Wish I could get it nowadays!
I use alot of taste enhancers in my currying, if you like MDH or Mangal products
you might want to give Kitchen King or Kashmiri Masala a go.
Oops 12.30am, I'll have to fire up the kitchen, I'm salivating, cheers.
