Garnish with fresh coriander and serve hot.
Switch off the flame. Sprinkle chopped cilantro on top, cover and let it rest for 5 minutes to allow the flavors to bloom. Serve warm with steamed rice.
TIPMosaranna is best enjoyed as a soup first, then mixed with rice — never boiling it after tempering destroys the delicate pepper notes.
What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Crush peppercorns coarsely; a fine powder makes rasam bitter and cloudy.
- 2Simmer until the rasam foams lightly on top — that signals perfect spice infusion.
- 3Add tamarind water gradually; taste as you go to balance sourness with salt.
- 4Pour the sizzling tempering immediately over the hot rasam for maximum aroma.
- 5Let the rasam rest covered for 5 minutes after garnishing — flavors deepen without boiling.
- 6For a thinner soup, add an extra ½ cup water before simmering the base.
