What is mattha?

Mattha is a classic Indian summer drink, also known as chaas or spiced buttermilk. It is made from yogurt or buttermilk and water, flavored with spices and fresh herbs. It is thin, cooling and salty-savory, not a sweetened flavored milk. Names and recipes differ by region and family, so the types below are common patterns rather than a fixed list.

What are the types of mattha?

Type What is in it
Plain chaas Yogurt, water and a little salt (and sometimes a little sugar), served over ice
Masala or spiced mattha Roasted cumin, ginger, mint, cilantro and optionally green chili, salt and a little sugar to balance
Herb mattha Heavier on mint, cilantro or curry leaves

How is spiced mattha made?

One recipe makes about 3 cups from 1 cup of plain thick yogurt, 2 cups of cold water, 1 teaspoon of roasted crushed cumin, 7 large mint leaves, 5 to 6 sprigs of cilantro, a 1-inch piece of ginger, one halved green chili (optional), and salt and a little sugar to taste. You blend the yogurt and water, add the herbs and spices, blend until smooth, taste, strain if you like, and serve cold over ice. Add more water if the yogurt is thick.

How is mattha different from lassi?

Lassi is typically thicker and often sweet, while chaas is thinner and usually salted and spiced. Some people also call plain buttermilk chaas, though traditional buttermilk is what is left after churning butter; most home chaas today is made from yogurt and water. Sources disagree on exact definitions, so use the name your family or region uses.

When is it served?

Cold, often after lunch or dinner or in summer, to cool the body and aid digestion, according to the recipe author. These are traditional uses, not medical claims.

Storage

Keep it in a glass jar in the fridge for a few days. The yogurt settles, so stir or shake before serving.

Tips

  • Use cold water if you serve it right away.
  • Roast cumin fresh for better flavor.
  • Strain for a smoother drink.
