Mattha (Marathi: मठ्ठा), also called Chaanch (Hindi: छाछ), (Nepali: Mohi/ मोही), (Marathi: ताक), (Tamil:மோர்),(Bengali:ঘোল),(Oriya:ଘୋଳ ଦହି,ଚଲ୍ହା),(Telugu:మజ్జిగా ) is an Indian spiced beverage made of buttermilk. Plain buttermilk is also called by Mattha. Other ingredients may include mint, roasted cumin seeds, asafoetida, curry leaves, salt and sugar. Mattha may also be smoked before serving for flavour. It is generally served before or after a meal, though it can also be consumed with the meal, and it is thought to help with digestion.
It used to be made of yogurt. The liquid that remained after churning butter was drunk as a cure for stomachaches or just as a refreshing drink in hot weather. More recently, it has been made using thinned-out yogurt, as it is used as summer appetiser in hot part of India.
