According to me Rasam or Soup(as mentioned usually by westerners) is a comforting food and also healthy and easy to make.Usually Ingredients used in Indian rasam like pepper, cumin,Corriander and sometime fenugreek is considered to aide digestion.The main ingredient may differ like tamarind paste or tomato purée or pineapple purée or lemon juice,dhal water or vegetable stock.
But this rasam sounded different in name and ingredients when I saw this in some channel( sorry don't remember the name as I was browsing through our new Asian tv connection)tried it the same day and we all liked it.Now it has become a part of mycooking every other week.
I found that there are many variations of this but personally I liked this way . Now coming to the recipe I would like to mention measurements are approximate .i did not make note of the measurements.and I did not remember the channel name to browse thru YouTube.
Green chilli -1
Garlic -1 or 2
