In Delhi, they call it...

One of the hangovers of the Madras Presidency days is that many people in the northern parts of India consider anything 'south of the Vindhyas' as being "Madrasi". And that was the explanation given to me by the shopkeeper at Dilli Haat when I asked him why this product was called 'Madrasi Saunf': "ye toh south mein log bahut khaate hain" - people in the south eat this a lot!
