In a bowl, take the yogurt and now add all the spices mentioned above.
Mix the spices and water well.
Now, in case you want a soft boondi raita then, add the boondi to the yogurt mixture now and keep it in the fridge. Take it out just at the time of serving and garnish with chopped Coriander leaves.
In case, you want a crisp raita, keep the yogurt mixture in fridge and add the boondi to the yogurt mixture just before serving and mix well. Garnish with chopped coriander leaves.
Serve chilled with paratha, pulao or biryani.
You can keep the consistency of raita as per your liking. If you want thick raita then go with the above mentioned quantity of water, but if you want little thin raita then increase the quantity of water.
In the warm places (or during summer), raita gets sour. You can avoid getting sour raita by adding salt just before serving only.
Store bought boondi is salted sometimes, so be careful with the quantity of salt in the raita.
