Jhalmuri is a popular street snack in the Bengali, Bihari, Bhojpuri, Odia, Assamese and Tripuri cuisine of the Indian subcontinent, made of puffed rice and an assortment of Indian spices, vegetables, Bombay mix (chanachur) and mustard oil. It is popular in the Indian states of Bihar, West Bengal, Tripura, eastern Uttar Pradesh, and Odisha and in neighbouring Bangladesh. It became popular in London when a British chef named Angus Denoon tried this snack in Kolkata and started selling it on the streets of London. The popularity of Jhalmuri has also reached other western cities like New York City through the Bengali diaspora.
