Raw Mango Kosambari Recipe (South Indian Mango Moong Dal Salad)
Raw mango kosambari is the kind of South Indian dish that comes alive when raw mango season rolls in. The recipe is having a moment online, with quick reels and pinned summer-salad boards showing off its bright green-and-yellow colors and the satisfying crunch of soaked moong dal. It is a no-cook salad in every sense that matters, since the only heat involved is the few seconds it takes to crackle mustard seeds in a small pan. The result is cool, tangy, salty, and lightly nutty all at once, which is exactly what feels right when the days start to warm up.
About This Dish
Kosambari (also written kosumalli or kosumbari) is a Karnataka classic that shows up on every Ugadi and Rama Navami plate, alongside panakam and neer mor. The basic idea is always the same: soaked split lentils, fresh raw vegetables, grated coconut, and a fragrant tempering. Versions across Karnataka and Tamil Nadu swing between cucumber-forward, carrot-forward, and mango-forward, depending on the season and the household. The raw mango version is the spring and summer favorite, built around the sour green mangoes that flood markets in those months.
Ingredient Notes
The dal of choice here is split yellow moong dal (hesaru bele), which only needs a 30-minute soak, no cooking at all. Look for a firm, sour green mango, the kind sold for pickles and chutneys, since a partly ripe one will throw off the balance. Fresh grated coconut makes a real difference, but thawed frozen grated coconut is a perfectly good substitute. Carrot is optional but adds color and a touch of sweetness, and cucumber keeps everything cool and crisp. For the tempering, coconut oil is the natural choice for a Karnataka salad, though a good quality ghee works beautifully too.
Method And Tips
The two technique points that separate a great kosambari from a mediocre one are dal soaking and tempering timing. Soak the moong dal for 30 minutes to 1 hour and no longer, because the grains should still bite back when chewed. For the tempering, let the mustard seeds finish crackling before adding the urad dal, then watch closely as it turns golden, since burnt urad dal will make the whole salad taste bitter. The final tip: hold back the lemon juice until just before serving. Adding it early pulls water out of the cucumber and mango, and a watery kosambari is a sad kosambari.
Serving Suggestions
Kosambari is at its best alongside a traditional South Indian meal, on a thali next to sambar rice, rasam, and curd rice. It is also a perfect light lunch on a hot day, eaten on its own with a wedge of lime. Once raw mango season comes around, give it a try and see how a handful of pantry ingredients turn into one of the freshest things on the table.

Ingredients
- For the salad
- 1/2 cup split yellow moong dal
- 1/2 cup raw green mango, peeled and grated
- 1/2 cup cucumber, finely chopped or grated
- 1/2 cup carrot, grated
- 1/2 cup fresh grated coconut
- 1 green chili, finely chopped
- 2 tbsp fresh coriander leaves, chopped
- 1/2 tsp lemon juice
- 1/2 tsp salt
- For the tempering
- 1 tsp coconut oil
- 1/2 tsp mustard seeds
- 1/2 tsp split urad dal
- 1/2 tsp cumin seeds
- 1 dry red chili, broken
- 8 curry leaves
- 1 pinch asafoetida (hing)
Instructions
- 1 Rinse the moong dal in 2 or 3 changes of water until the water runs clear. Soak the dal in plenty of room temperature water for 30 minutes, then drain thoroughly in a fine mesh strainer. The grains should be tender enough to bite through but still hold a gentle crunch.
- 2 While the dal soaks, peel the raw mango and grate it on the large holes of a box grater. Grate the carrot the same way, and finely chop or grate the cucumber. Chop the green chili and coriander leaves.
- 3 In a medium mixing bowl, combine the drained moong dal, grated mango, cucumber, carrot, fresh coconut, green chili, and salt. Toss gently with a spoon so the dal does not get crushed.
- 4 Heat the coconut oil in a small tempering pan over medium heat. When the oil shimmers, add the mustard seeds and let them crackle for a few seconds.
- 5 Add the urad dal and cumin seeds. Stir for 15 to 20 seconds until the urad dal turns light golden. Add the broken red chili, curry leaves, and a pinch of asafoetida, then immediately switch off the heat so the spices do not burn.
- 6 Pour the hot tempering over the salad and fold everything together so the flavors coat the dal evenly.
- 7 Just before serving, squeeze in the lemon juice and stir once more. Taste and adjust salt or lemon as needed. Serve at room temperature or lightly chilled.
Notes
- Add the lemon juice only right before serving. If added too early, the salt and acid pull water out of the vegetables and the salad turns watery.
- Use a firm, sour green mango. If the mango is even slightly ripe and sweet, skip the lemon juice entirely and taste before adjusting.
- Soak the dal for no more than 1 hour. Longer soaking softens the grains too much and they lose the signature kosambari crunch.
- Leftovers keep refrigerated for up to 1 day, but the salad is best within a few hours of mixing.
