Raw mango rasam

Rasam is South India's 'consommé'. This thin, spicy soup traditionally serves to stimulate digestion at the end of a meal. Using raw (green) mango is a genius twist: the fruit's natural acidity replaces tamarind, giving a fresh, fruity tartness alongside the pungent pepper and cumin. One sip and you feel it warming you through.

Instructions

1

Rinse the lentils and boil in salted water until soft (approx. 15-20 mins). At the end, mash slightly with a fork to cream the soup.

Tip: Red lentils cook apart quickly, no soaking required.
2

Peel and cube the mango. Chop the onion and garlic, slice the chillies.

Tip: The acidity of the mango replaces vinegar; it is a natural flavouring.
3

Heat oil in a saucepan. Throw in the cumin, let sizzle for a few seconds, then add the onion and garlic. Sauté until translucent.

Tip: This 'blooming' of spices builds the foundation of flavours in the oil.
4

Add the tomato, chillies, mango and spices (coriander, pepper, curry leaves). Simmer until the tomato becomes mushy.

Tip: In the juice of the tomato and mango, the spices won't burn but meld together.
5

Pour in the cooked lentils and enough water to get a thin soup consistency. Season with soy sauce and salt.

Tip: The essence of Rasam is the thin, spicy broth; it shouldn't be stew-thick.
6

Boil together for 5-10 minutes. Finally, squeeze in lemon juice to taste.

Tip: Always add lemon juice at the end of cooking to preserve the fresh Vitamin C and aroma.

Recipe FAQ

I can't find raw mango, what should I do?
You can use underripe, hard mango, or substitute with more lemon juice and tamarind paste.
It's too thin.
Rasam is meant to be thin, like a tea. But if you want to thicken it, mash more cooked lentils into it.
