Sources to mention: Academic texts on viral media, social media studies, perhaps case studies from journalism. Also, citing how other street foods have been represented in media could provide a broader context.

Possible challenges: Without specific details about the video, some assumptions might be necessary. Also, verifying the origin and impact of the video could be tricky, but general knowledge of social media trends in India can help. I might need to refer to similar cases for structure and themes.

In conclusion, the paper should not only describe the event but also situate it within the broader context of how social media influences cultural narratives and food economies, while touching on the challenges of managing viral content.
