Papdi are made with whole wheat flour or all purpose flour and sometimes spiced cumin or carom seeds or both. They are small round savory crackers that are deep fried. You can buy them in grocery stores or supermarkets or sweets shops if you live in India or make at home. If you live outside then look for them in Indian grocery stores or buy online. Papdi is often added to chaat snacks like bhel puri, ragda chaat, sev puri and dahi bhalla. They can also be eaten as is like a crispy cracker or served as a side with a cup of Indian chai.
