(off topic) Balti has a rather typical "Bengali" style to it (or Bengali-British). Other side of the Subcontinent (rather than [current] Pakistan side).

I magically made balti one day when I was making a typically Punjabi (often assumed the generic North Indian style of food) one day but changed it by adding a can of *coconut* milk!

I don't know how exactly they make balti in London, by my coconut milk concoction tasted to me "just like" the balti-s I ate there!
