Lemon Thyme Rasam Recipe is a wonderful twist to one of the most regular side dish of South India - rasam. Rasam is a part of a traditional South Indian household, served with rice, poriyal and appalam.  Thyme is a beneficial herb added into this rasam recipe with its positive benefits of smell, flavour and digestive properties.

Did you know: Thyme is helpful in combating sore throat and eases cough and bronchitis. It is a lesser known fact that thyme boosts mood due to a natural chemical called carvacrol in it. Carvacrol boosts production of dopamine and serotonin.

Serve Lemon Thyme Rasam Recipe with steamed rice and beetroot poriyal for a satisfying meal.

You may want to reduce the quantity of thyme added to the Thyme rasam – I have suggested 1 tablespoon for 3 cups of water, however you could first try with half a tablespoon and then add more depending on how strong you want the thyme flavours to be.

If using dry thyme, then take just half of quantity suggested for fresh leaves.
