BHELPURI (RICE POPCORN)

• A snack with almost iconic status in Western India, bhelpuri is low-fat, nutritious and delicious. It is a puffed rice dish with various vegetables and a tangy tamarind sauce. It is a type of chaat, or small plates of savoury snacks.
  

• Bhelpuri is best consumed as soon as it is made. If left for a while, the juices from the tomatoes, chutneys and peanuts will combine to render the puffed rice soggy. A dry variant of Bhelpuri popularly known as Bhadang is consumed after garnishing with onions, corriander and lemon juice.
