I've noticed from here and other sources that for BIR style curries the spice mix usually contains proportions (in roughly descending order) of Turmeric, Corriander, Cumin, Paprika and Curry powder.
I wonder what the origin of this spice mix is. I've searched for Bangladeshi and Bengali recipes but not found anything similar.
Last weekend I made to spec the Lamb Shank Korma from the "50 Great Curries Of India" book. This has corriander powder but no cumin and no turmeric whatsoever. It does have garam masala and mace.
My wife liked the result almost as much as my BIR efforts (much to my horror) but for me using too much mace or nutmeg can result in something tasting like toothpaste or cough medicine!
I've searched through a Madhur Jaffrey book I've had for years and once again there is nothing like our BIR spice mixes to be seen, and the use of turmeric tends to be low quantities.
I just wondered whether anybody knows what the origin of our BIR spice mix is.
I'm not complaining - it works for me but just curious.
Paul.
