Moru Curry sans Coconut and Oil

Though I got over with the flu, the after effects are still lingering. Primary one is the loss of appetite - I can't stand any food at all. One way it is a blessing in disguise; when the majority  of the world is making  new year's resolutions to somehow reduce their weight, here I am able to achieve it without effort! I feel so full by just the smell of food and even my favorite dishes, I can't make myself to eat.
I had been getting a lot of advice from my moms about how to revive my appetite - one such suggestion from my MIL was to have a cake that I like - she knows me too well, I guess. But that plan didn't work as I couldn't even tolerate a single bite. So my mom suggested that I try this with some rice. Though I couldn't eat much of rice, I did end up having this as a soup.
This oil and coconut free recipe is originally by my grand mother, especially for the times when anyone was sick in the family.

Buttermilk/Curd (whipped)-1 glass
