Instructions
Roast the coriander seeds and jeera seeds in a few drops of oil on medium heat until fragrant and remove from heat. Make sure not to burn them.
Next roast the dry red chillies in a few drops of oil until fragrant.
In the same pan, dry roast the horsegram/kudu on medium heat until it starts giving off a toasted fragrance. It may also splutter. Make sure not to burn them.
Defrost coconut, if using frozen, in the microwave.
Add coconut, roasted spices, tamarind into a blender with ¼ cup water and make it into a paste.
Transfer the paste into a pot and add in the 2-3 cups of water depending on how thick or thin you need the rasam.
Add salt and jaggery.
Bring the saaru to a boil. Boil gently for five minutes.
Turn off the heat.
Variation 1 of Oggarane/tadka/tempering (With hing)
In a small pan, heat 1-2 teaspoon of oil. When oil starts glistening, add mustard seeds and dry red chilli. When mustard seeds start spluttering add the cumin seeds and hing. Add curry leaves.
Pour the fragrant hot oil with the spices over the saaru. Cover with a lid.
Variation 2 of Oggarane/tadka/tempering (with Garlic)
In a small pan, heat 2 teaspoon of oil and add garlic. When garlic starts turning golden, add the mustard seeds, cumin seeds and dry red chilli. When mustard splutters, add curry leaves.
Pour the fragrant hot oil over the saaru. Cover with a lid.
Tip : If curry leaves have water on them, they cause oil to splutter and cook-top can get messy. So place the curry leaves on top of the saaru and pour the hot oil over the curry leaves!
Serve with rice.

Notes
If jaggery is unavailable, use coconut sugar/palm sugar/mexican piloncillo instead.
Coconut needs to be at room temperature when blending, if not the fat separates.
The saaru/rasam thickens slightly on cooling down.
The colour of the rasam depends on the dry chillies used. Byadgi and kashmiri varieties give a brighter colour.
