Indian spiced butter milk traditionally known as "Mattha" is a tangy yogurt drink flavored with ginger-green chili paste and fresh cilantro. With very few ingredients this cold beverage is quite refreshing especially in summer. There might be variety of versions to make mattha but this is a very traditional Maharashtrian recipe, just like my mom makes it. Ingredients 4 cups plain buttermilk 2 green chili's 1 inch ginger  2-3 tbs fresh chopped cilantro Salt as per taste 1 tsp sugar Method Method is quite simple. Mix yogurt and water together to make homemade buttermilk. It should be thin in consistency. To make mattha, add all the ingredients in a blender and blend it for few minutes until little bit frothy.  Pour in a glass and enjoy a refreshing drink!!
