Get ready with all the ingredients. Take a lemon sized tamarind and soak in water and squeeze.
In a mixer grinder add all the ingredients except tamarind juice and grind it to a coarse mix.
In a non- stick pan add a teaspoon of oil on a medium heat. To it add crushed garlic, mustard seeds, urad dhal and gram dhal and let it crackle. Then add little asafoetida to it.
Add coarse grind mixture to the tamarind water and mix well. To it add 1 to 1 ½ cup of water and add to the seasoning. Make sure the seasoning mixture is not browned.
Add salt to taste. Wait until froth forms on top of the mixture. Do not allow the mixture to boil. Once the froth forms switch off the heat and garnish with curry leaves and coriander leaves and transfer it to a serving bowl.
