This is a great lemon flavoured version which is as delicious as it is tangy and warming to body and soul. Believe me when i say this is the ultimate soul food as there is nothing more appealing to a south indian on a cold winter day than a bowl of hot boiled rice ladled over with delicious lemon rasam, drizzled with a tsp of ghee with a side of potato roast (always welcome) and the must have papads! lemon rasam does not use tamarind as we use in pepper and other rasams as the lemon juice fulfils the sour and bitter additions. For the knowledge of the rest of the ingredients lets go on to the recipe!.
