Chaas (Indian Buttermilk)
Chaas is a curd or yogurt-based Indian drink derived from the Sanskrit word Chacchika. This means churned yogurt or cultured milk from which butter has been removed.
Buttermilk is English term. In magahi, it is called mattha, ghol in Rajasthan & bengal , chaash in odia, moru in tamil & malayalam, taak in marathi & konkani, majjige in kannada, ale in tulu.
Buttermilk is served every day at the end of the meal as it helps in digestion, washes fat, and fights acidity. On a long, hot, and tiring day, the first thing my family loves to have is tempered buttermilk (phanna taak or oggarane majjige). It helps keep your body cool.
This curd based drink tastes the best when served chilled. So make a big batch and store it in the refrigerator in advance. Serve it after a meal or when you are home from the hot weather during summer.

Ingredients
Buttermilk: If homemade buttermilk is unavailable, you can dilute the yogurt with water and use it to make this drink.
Spices: Green chilies, ginger, and coriander leaves add a unique kick and warmth to the chaas.
Salt: Plain salt and black salt add taste.

Delicious! perfect for someone who finds excuses to not have curd or buttermilk. I substituted mustard seeds with jeera and added green chilly and had it in winters.
