Soak the tamarind in warm water for at least 10 minutes. Then, squeeze it thoroughly to extract thick tamarind juice and set it aside, ready for making the Vatha Kuzhambu paste.
2 small lemon size Tamarind
Heat the pan and add approximately 1 teaspoon of gingelly oil.
1 teaspoon Gingelly Oil
Add the following ingredients to the pan one by one—coriander seeds, chana dal, urad dal, whole pepper, Fenugreek seeds, and red chili—then sauté until fragrant. Ensure the ingredients do not burn by frying them over medium flame, stirring continuously.
2 tablespoon Coriander seeds, 2 tablespoon Urad Dal, 1 tablespoon Peppercorns, 1 teaspoon Fenugreek seeds, 10 nos Red Chili, 2 tablespoon Split Bengal Gram (Channa Dal / Kadalaparuppu)
Transfer the fried ingredients to a mixer and grind them into a fine powder once they have cooled.

1 teaspoon Ghee, 3 tablespoon Sundakkai Vathal (Dry Turkey Berry)
In the same pan, add about 3 tablespoons of gingelly oil. Once the oil is hot, add mustard seeds and let them sputter. Then, add chana dal and sauté until golden. Finally, add curry leaves and mix well.
3 tablespoon Gingelly Oil, 1 teaspoon Mustard seeds, 2 teaspoon Split Bengal Gram (Channa Dal / Kadalaparuppu), 1 sprig Curry leaves

Add Turmeric Powder, Hing, Salt and mix well. Allow this mixture to boil in medium flame.
1 teaspoon Turmeric Powder, 2 teaspoon Salt, 1 teaspoon Asafoetida (Asafetida / Hing)
Cover the pan with a lid and let the kuzhambu mixture simmer until the oil separates from the Kuzhambu.
