Vathal Kolambu Recipe

If using store-bought dried vathal (drumstick or mixed), soak in 1 cup hot water for 10–15 minutes to rehydrate. Drain and reserve the soaking water. If making vathal at home, rehydrate until pliable but not mushy.

Mix 2 tbsp tamarind paste with 1 cup warm water. Stir and break up any lumps. Set aside for flavors to marry while you prepare the spice paste (about 10 minutes).

Dry-roast the whole spices

In a small skillet over medium heat, dry-roast 6 dried red chilies (stems removed), 2 tsp coriander seeds, 1 tsp fenugreek seeds, 1 tsp cumin seeds, 6 black peppercorns, 1 tsp urad dal and 1 tsp chana dal. Roast for 2–3 minutes until fragrant and the dals turn light golden. Remove and cool.

In the same skillet, add a pinch of asafoetida and 8 curry leaves; fry for 20–30 seconds until crisp. Cool these with the roasted spices.

In a blender, add the cooled roasted spices and curry leaves, 5 shallots (peeled), 4 garlic cloves (if using), and about 1 tablespoon water. Grind to a smooth paste. Add a little more water if needed to get a medium-thick paste. Set aside.

Heat 3 tbsp oil in a heavy-bottomed pan over medium heat. When hot, add 1 tsp mustard seeds. When they splutter, add 1 tsp urad dal and 1 tsp chana dal. Fry until the dals turn golden brown.

Add 10 curry leaves and 8 sliced shallots. Sauté until shallots are translucent and starting to brown at the edges (4–5 minutes).

Add 1 tsp turmeric powder and stir for 20 seconds to release aroma.

Add the prepared spice paste to the pan and sauté for 3–4 minutes on medium-low heat, stirring frequently so it does not stick. Cook until raw smell disappears and oil begins to separate slightly.

Pour in the tamarind water (strained if you prefer clear gravy) and the reserved vathal soaking water (if any). Stir well and bring to a gentle boil.

Add the rehydrated vathal pieces (1 cup). If you are using store-bought already rehydrated pieces, add them now. Add 2 cups water (or adjust to desired consistency) and salt (1.25 tsp). Stir to combine.

Lower heat to a simmer and cook uncovered for 12–15 minutes, stirring occasionally, until the vathal has softened and the flavors have melded. If the gravy thickens too much, add small splashes of water to reach the preferred consistency.

Taste and adjust seasoning. If the tamarind is very sour, add 1 tsp jaggery or brown sugar to balance. Simmer another 2 minutes.

Turn off heat and stir in 2 tbsp freshly grated coconut (or dessicated coconut rehydrated briefly) into the kolambu for texture and mild sweetness.

In a small tadka pan, heat 1 tsp oil. Add 1 broken dry red chili and 6 curry leaves and fry for 15–20 seconds until crisp. Pour this hot tempering over the kolambu. Cover immediately for 1 minute to trap aroma.

Give the kolambu a final gentle stir and transfer to a serving bowl.

Serve hot with steamed rice, idli, dosa or as part of a South Indian meal. Vathal kolambu is typically an entrée accompaniment that pairs best with plain rice and fried or steamed lentil-based sides.
