Once upon a time a bengali visited puri (lord JAGAGNNATH)and tasted our sweet rasgolaa , and did some make over to the sweet . Since west bengal is more advanced than Odisha they are taking the benefits .
As it was used as Prasad since a long at Lord Jagannath Temple,Copy of Rasogolla should not be done. If Bengal copy it than the name cane be designed as Jagannath Rasogolla.Other wise it will like a remake film in other language.
