Manathakkali Keerai Kadaiyal is a beloved traditional Tamil dish made with black nightshade leaves, a humble green that has been cherished in Tamil kitchens for generations. Known botanically as Solanum nigrum, this leafy green holds a special place in South Indian cooking, particularly in Tamil Nadu. The word 'kadaiyal' refers to the technique of mashing or churning the cooked greens to create a thick, comforting gravy that pairs beautifully with steaming hot rice and a drizzle of sesame oil or ghee.
Tamil families have long turned to manathakkali keerai not just for its incredible taste but also for its powerful medicinal properties. This greens gravy is a go-to remedy in every Tamil home for healing mouth ulcers and stomach ulcers, cooling the body during hot summers, and soothing digestive issues. Grandmothers across Tamil Nadu would lovingly prepare this dish during summer months or whenever a family member needed gentle healing food. It is a dish rooted in care, tradition, and the wisdom of Tamil home cooking.
What makes this recipe truly special is how simple and quick it is to prepare at home with minimal ingredients. The secret lies in using fresh manathakkali leaves and cooking them gently with toor dal, tamarind, and a simple tempering of mustard seeds, dried red chillies, and shallots. The mashing technique gives the gravy its characteristic thick, hearty texture. For best results, always use fresh leaves, do not overcook the dal, and finish with a generous pinch of asafoetida for that authentic Tamil flavour and aroma.

Instructions
💡 Tap a step to mark it doneSoak the tamarind in 1/4 cup of warm water for 10 minutes, then squeeze and extract the tamarind juice. Discard the pulp and set the tamarind water aside.
Wash the toor dal thoroughly under running water. Pressure cook the toor dal with 1 cup of water and a pinch of turmeric for 3 to 4 whistles until soft and mushy. Once the pressure releases, mash the dal well with a ladle and set aside.
Heat sesame oil in a heavy-bottomed kadai or pan over medium flame. Once the oil is hot, add mustard seeds and allow them to splutter fully. Then add cumin seeds and let them sizzle for a few seconds.
Add the dried red chillies and curry leaves to the pan and fry for 30 seconds until fragrant. Then add the sliced shallots and crushed garlic. Sauté on medium flame for 4 to 5 minutes until the shallots turn golden and soft.
Add the chopped tomato to the pan along with a pinch of salt to help it cook faster. Sauté for 3 to 4 minutes until the tomato becomes completely soft and the raw smell disappears and the mixture comes together as a base.
Add the turmeric powder, red chilli powder, and coriander powder to the pan. Mix everything well and cook the spices on low flame for 1 to 2 minutes, stirring continuously so the spices do not burn.
Add the cleaned manathakkali keerai leaves to the pan. Stir well to coat the leaves with the spiced onion-tomato base. Cook the leaves on medium flame for 3 to 4 minutes, stirring occasionally, until the leaves wilt down and reduce in volume.
Pour in the tamarind extract along with 1 cup of water. Add salt to taste. Stir well, bring to a boil, then reduce to medium flame and let the gravy simmer for 6 to 8 minutes until the raw tamarind smell cooks off.
Add the mashed toor dal to the pan and mix it thoroughly into the greens and tamarind gravy. Stir well to combine everything evenly. Add a little more water if the gravy is too thick and adjust consistency as needed.
Using the back of the ladle or a wooden churner (matthu), gently mash and churn the greens in the gravy. This kadaiyal technique breaks down the leaves slightly and gives the gravy its signature thick, hearty texture. Do not blend completely — some texture is ideal.
Add the asafoetida at this stage and stir it in. Taste and adjust salt and spice levels as needed. Let the gravy simmer on low flame for another 2 to 3 minutes so all the flavours come together beautifully.
Turn off the flame. Finish with a drizzle of fresh sesame oil on top for extra aroma and authentic Tamil flavour. Serve hot with steamed white rice, papad, and a small piece of raw onion on the side.
Tips and Tricks
- Always use fresh manathakkali keerai for the best flavour and medicinal benefits. Wilted or old leaves can turn the gravy slightly bitter, so buy and cook on the same day when possible.
- Sesame oil (gingelly oil) is essential for authentic Tamil kadaiyal — do not substitute with refined oil as it changes the flavour profile significantly. The sesame oil also enhances the cooling properties of the dish.
- Do not skip the mashing (kadaiyal) step — this technique is what gives the dish its name and its characteristic thick, rustic texture that clings beautifully to rice. A traditional wooden matthu churner gives the most authentic result.
