Chaat masala is a masala, or spice mix, used in Indian and Pakistani Cuisine. It typically consists of amchoor (dried mango powder), cumin, Kala Namak, coriander, dried ginger, salt, black pepper, asafoetida and chili powder. The ingredients are combined and served on a small metal plate, polystyrene plate or a banana leaf, dried and formed into a bowl, at chaat carts (especially in Gujarat, Maharastra, Punjab, Sindh and across Northern India, Pakistan and even Southern India).
Chaat masala has both sweet and sour taste. It is used to flavour all the popular fast foods of India and Pakistan like bhelpuri, golgappa, aaloo chaat and Dahi puri. It is something of an acquired taste, and can be added to all sorts of everyday foods and drinks or even eaten on its own.
