Summers are the time of never ending thirst, when appetite goes for a toss and all we want is something cool, filling and at the same time light also. This Indian Buttermilk /Chaas with spices is perfect refreshing drink that is not only delicious but also aids in digestion and cools down the body!!

Indian summers, especially North India are very harsh and people rely on natural coolants different beverages, fruits like watermelon, different melons and salad veggies like cucumber, kakdai a different kind of cucumber, different varieties of gourds(bottle gourd, ridge gourd) and yogurt based drinks and curries.

Yogurt or Curd or Dahi popularly called in Indian households is widely used in summers for different kind of drinks, curries and dips or side dishes raita.

Lassi one of the most popular drink and another is Chaas or Mathaa (Spiced Buttermilk) with spices like cumin, black salt and herbs like cilantro/mint/ginger. Chilled glass of Chaas kills of the heat instantly and also makes filling snack for quick hunger pangs.

What is Chaas/Mathaa

Chaas/Mathaa is a yogurt based drink, that is good for body and aids digestion. It cools and dehydrates the body in summers and many times used in Ayurvedic treatments for stomach and skin disorders.It is very popular in Indian Sub Continent, and is served with or after meals.

Traditionally Chaas is made by churning chilled thick yogurt with chilled water, separating the milk fat(butter) from it. I remember my mom making Chaas by blending yogurt with water with wooden churner, separating little butter that was formed by churning.

I also remember my maternal grandmother and other females in our ancestral village churning butter in morning (in summers) from the yogurt that was set the previous night and used the whey for drinking as Chaas or Mathaa(in local language).

Nowadays many people make Chaas by diluting one part yogurt with 3-4 parts of water (that’s the way I too make), as churning out butter from it may take a long and with many using store-bought yogurt, you get a very negligible amount of butter.

Benefits of Chaas

Chaas is very good for stomach related problems. Some of the benefits of having Chaas:

  • If you feel bloated after heavy meals, having some buttermilk makes you feel lighter instantly. The herbs and spices and buttermilk aids in digestion relieve, stomach problems associated with gas, acidity, and constipation.
  • These days buttermilk is also a part of weight loss diets and programs as one of the detox drinks for it body cleansing properties.
  • Sipping on the buttermilk during fasting helps to keeps the energy level up and keeps away the hunger pangs. Use sendha namak (Rock salt if you don’t use table salt when fasting).
  • Do you know it a very good cleanser for skin and hair. Apply a spoonful buttermilk with a pinch of Turmeric to get a shiny, skin free of acne and pimples.For hair message about half cup of buttermilk without salt on scalp. LEave for 10-15 mins and then shampoo. Gives you very silky and smooth hair.
  • One of the best electrolytes in diarrhea. Add a pinch or two of salt and some crushed dry roasted cumin, in a glass of Chass made with one part yogurt and 4 parts water to relieve the upset stomach.

Commonly used spices and herbs as per individual’s choice used for flavoring Chaas/Buttermilk:

Fresh Coriander Leaves(Dhania Patte), Fresh Mint Leaves (Poodina Patte), Fresh Ginger, Ginger Powder(Sonth), Black Pepper (Kali Mirch), Dry Roasted Cumin (Bhuna Jeera), Green Chillies, Black Salt(Kala Namak), Sugar. As per Ayurveda these herbs and spices can be used in different combinations for curing stomach skin disorders.

How to make Roasted Cumin Powder

Roasted Cumin Powder is used in many Indian Appetizers, curries and fruit salads. You can easily make it at home.Freshly roasted and ground Cumin powder is much more flavorful than the store bought packaged one.

To make it at home, take 1-2 tbsp or if you need more take 1/2 Cup. Dry roast in a pan /griddle on low heat. When the aroma of roasted cumin starts to come, take out on a plat or dish. Cool and then grind it coffee grinder or crush and make powder with rolling pin.

How to make Chaas/Mathaa or Indian Buttermilk

You can make Chaas within 5 mins.. Just crush the herbs, mix everything.

Make it in blender or make in a bowl. If you don’t have the churner then you can use balloon whisk..Even your kids can make it very easily.

I make it almost everyday or alternating with other yogurt preparations.My kids love to have it when they come back after school. It is one of the best detox drinks also, you can have for breakfast or anytime during the day if you are fasting on weight loss diet.

Another, tip to add on the yumminess is add 1-2 tbsp of Boondi/fried chickpea balls, in it. Chaas with Boondi is served in many places in Western U.P, especially when guests come. It makes a good filling appetizer or accompaniment to meals.
