Paruppu Urundai Kuzhambu

Soak the chana dal in enough water for at least 2 hours. This softens the dal and makes it easier to grind into a coarse mixture for the dumplings. Do not soak for too long or the dumplings will become too soft and break apart in the gravy.

Drain all the water from the soaked chana dal completely. Transfer it to a mixer grinder along with green chillies, ginger, and a pinch of salt. Grind coarsely without adding any water. The mixture should be thick and hold its shape when pressed between your palms.

Transfer the ground dal mixture to a bowl. Add finely chopped curry leaves, a pinch of fennel seeds, and salt to taste. Mix everything well. Divide the mixture into small equal portions and roll them gently into smooth round balls or urundais. Set aside on a plate.

Soak the tamarind in 1.5 cups of warm water for 10 minutes, then squeeze and extract the thick tamarind juice. Discard the pulp and seeds. Set the tamarind water aside for use in the gravy.

Heat sesame oil in a wide, heavy-bottomed kadai over medium heat. Add mustard seeds and let them splutter. Then add cumin seeds, dry red chillies, and curry leaves. Sauté for 30 seconds until aromatic.

Add the finely chopped onion to the kadai and sauté on medium flame until it turns golden brown. This step is important as caramelized onions add a natural sweetness and depth to the kuzhambu. Add the garlic cloves and sauté for another minute.

Add the chopped tomatoes to the pan and cook until they become completely soft and mushy, and the oil starts to separate from the masala. This should take about 5 to 6 minutes on medium heat. Stir frequently to prevent burning.

Add turmeric powder, red chilli powder, coriander powder, and sambar powder to the tomato-onion masala. Mix well and cook the spice powders for 2 minutes on low heat so they are well roasted and the raw smell disappears completely.

Pour in the extracted tamarind water and stir well to combine with all the masala. Add 1 more cup of water to adjust the consistency of the gravy. Season with salt and bring the kuzhambu to a rolling boil over medium-high heat.

Once the kuzhambu is boiling, gently drop the prepared paruppu urundais one by one into the gravy. Do not stir immediately. Let the dumplings set in the gravy for 2 minutes before gently shaking the pan to move them around. Avoid stirring with a spoon as the dumplings can break.

Grind the grated coconut with a little water into a smooth paste. Add this coconut paste to the kuzhambu and stir gently. Lower the heat to a simmer and cook for 8 to 10 minutes until the urundais are fully cooked through and have absorbed the flavors of the gravy.

Check the seasoning and adjust salt if needed. The kuzhambu should have a medium-thick consistency. Garnish with freshly chopped coriander leaves. Serve hot with steamed white rice and a small drizzle of ghee for an authentic Tamil meal experience.
