Tamil rasam

I learned this from my relative. There is one good point about this dish.I have accidentally found out that this is the best medicine for running nose.Drink it before going to bed (if you are not allergic to pepper or any other ingredient in this dish) and get up from the bed in the morning feeling fresh with clear nasal passages.
Usually, I make it in 2 forms: diluted and concentrated.
Concentrated form during meals along with rice and the diluted one to drink directly.It tastes awesome when you drink rather than eat with rice.Measurements given here are highly approximate.
My grade for this dish is Excellent
