India is a home for sweets. the country has various cultures in different parts of the same. The food habit of the people of different cultures are different too. This provides a variety in food thus the sweets.
You can enjoy rasogolla and sandesh in Kolkata, West Bengal but you can find MIshri-mawa only in Jaipur, Rajasthan. Jalewa of Indore (M.P.) tastes good and for Peda you have to visit Varanasi. Pista lodge in Delhi, the capital of India and Kolhe ka petha from Agra (U.P.), the city of Taj. Laddu is ever green all over India.
That would make an excellent travel brochure xD. It seems interesting that you can only get it in one area, thats like saying you can only by Cake in Town B and Ice Cream in Town C, so where is Town A with Ice Cream Cakes?
It is not the matter that you can get some thing in one place and it will not be in other place but it is a matter of where it is the best. I have already published a hub on Rasogolla and Sandesh. May I write some more if you feel it tasty.
