Chaach is basically a homemade skimmed buttermilk – the watery, milky liquid that’s left over when butter is made. It is slightly sour and contains fragments of curd.
The commercially available buttermilk is made with a shorter fermentation time of around 12 hours, with a process quite similar to making yogurt.
As the butter is already skimmed off it, Chaach becomes a low fat liquid which is three times quicker to digest than milk. The lactose in milk gets transformed in lactic acid and the live culture reduces the bad bacteria in the stomach, improving digestion. That’s exactly why in Ayurvedic healing, Chaach is highly recommended with or after meals to reduce gas and bloating.
If you don’t churn butter at home then obviously you don’t have buttermilk at hand either, but that doesn’t mean you can’t enjoy this delicious coolant in summer. There are two easy ways to make butter milk at home; one is by adding vinegar or lemon juice to warm milk. Just add two tablespoons to 1 litre of warm milk and wait a few minutes for curd to separate, leaving behind buttermilk. Pass it through a cheese cloth and you will get homemade paneer cheese as a bonus.
The other way which is my favourite is easier and makes tastier Chaach; just dilute yogurt with lots of water to make instant Chaach or Chaas. This method is used in many South Asian homes to make use of sour yogurt. The whole concept of making a drink out of butter milk or sour yogurt is about saving good, healthy food from getting wasted.
To revive those fond childhood memories, I still make Chaach for my family by churning yogurt and cold water in a little claypot with a similar but much smaller, handy little wooden whisk. The features that differentiate Chaach from lassi are that Chaach is much more diluted, flavoured mostly with salt, mint, spices or rose water and has lots of froth on top.
Combined with mint, it makes a summer cooler like none other!
