First soak the tamarind in a cup of warm water along with salt for atleast 15 minutes. Make 3 cups of tamarind extract out of it by adding required water.

Now grind roughly all the ingredients listed under "To Grind", except garlic, using mortar and pestle / mixie. Finally add garlic to the other ground ingredients and pulse one or twice until you get a coarse paste. Keep it aside.

Now using your clean hand just mix them together by crushing the tomatoes, curry leaves and cilantro sprigs roughly in the tamarind extract. This way helps you to get the flavors infused into Rasam.

Now heat a pan with oil, add the mustard and once it splutters, add the other ingredients listed under "To temper", in the given order. Once the broken urad dal starts changing color, pour the prepared tamarind extract mixture to the pan. Be careful while pouring the rasam into the hot pan because it would splutter.

Within few minutes there will be a froth/bubbles formation on the top and the rasam will just start to boil. Turn off the flame immediately and transfer to the serving bowl.
