Ok thanks Guys! Add to this I sometimes find a star anise in Do piazas. Now this is a real treat!!
Sounds like South London may be the place for whole spices! Having said that, madras and vinds are smooth as the proverbial (as they should be).
I haven't heard much from the Midlands (balti belt). Are these so regional that they are not considered BIRs? Not having visited, how do they compare? I sometimes get the impression that Balti is just another standard dish round my way and has no real link to the the pan. The menu will often wax lyrical about special herbs and spices, cooked in an authentic balti pan. Cobblers! I bet its cooked in identical pan as my chicken madras. It may get served up in a pan with 2 handles! In fact it tastes like other house curries, with perhaps more garlic and ginger, plus chunky veg. Considered tad overpriced for what they are.
