Kadhi is a soup like, yogourt based curry. It is often served with Khichdi although some people prefer to drink it on its own. It is another great vegetarian option (as long as you are okay with milk products). When I have a bad cold, I like to make my kadhi extra spicy and drink it to clear my sinuses. I also think the turmeric in it helps since turmeric is supposed to have strong anti-inflammatory properties.
