Chaat masala (also spelled chat masala) is a masala, or spice mix, used in indian cuisine. It typically consists of amchur (dried mango powder), cumin, kala namak, coriander, dried ginger, salt, black pepper, asafoetida and capsicum. The ingredients are combined and served on a small metal plate or a banana leaf, dried and formed into a bowl, at chaat carts (especially in southern-india).
Chaat masala has a pungent smell and tastes both sweet and sour. It is used to flavour all the popular fast foods of india like bhelpuri, golgappa, aaloo chaat and dahi puri. It is somewhat of an acquired taste and can be added to all sorts of everyday foods or even eaten on its own.
