No Mix Powder - No Bir style cooking - No debate. ;D ;D ;D
Present a BIR Chef a jar of Schwartz or any other housewives choice curry powder
and you would be laughed out of their kitchen...Numbnuts need not reply :

For the interested, "MIX powder" is a Bangladeshi kitchen term for exactly what it is.
the Chefs mix of spices, used in his kitchen/cooking. (Base Spices)
Just like "Garabi" is the term for the onion gravy. (Base)
The point being, they are specific kitchen terms for two clearly defined and identified items
used daily in BIR kitchens
I also posted a couple of years ago, when I spotted a forward thinking company (IBCO)
had brought out a ready mix, aimed at BIR.
