Mah Korai Axoni Dal

Method

1. 1

   About Mah Korai Axoni Dal: Axoni (also spelled akhuni) is Assam's fermented soybean — a small, brown, deeply fermented bean cake with an intensely savoury, almost cheesy character. Used in tiny amounts, it transforms ordinary lentil dishes into deeply umami-rich curries. Mah Korai Axoni Dal is the household name for red lentils cooked with this fermented soybean, producing a dal unlike any other in Indian cooking.

2. 2

   Source axoni: Find axoni at Northeast Indian groceries or specialty Asian markets — it is sold in small dark blocks or jars. The smell is strong and pungent (similar to fermented black bean paste in Chinese cooking, or natto in Japanese). Strong smell is normal and expected; truly off axoni smells rancid rather than fermented.

3. 3

   If you cannot source axoni: Use 1 tbsp Korean doenjang (fermented soybean paste) or Japanese miso (red miso preferred) as a substitute. Both deliver the umami fermented soybean character, though the Assamese flavour profile will differ slightly.

4. 4

   Measure carefully: A little goes a long way. Use 1/2 cup of axoni for this recipe — but it should equal about 2 tbsp by mass once measured (axoni is dense and concentrated). A heaping tablespoon would also work for a milder version.

5. 5

   Choose red lentils: Use 1 cup of split red lentils (masoor dal) — the small salmon-orange split lentils that cook fast in 20 minutes without soaking.

6. 6

   Wash thoroughly: Wash the lentils in 4-5 changes of cold water until the water runs nearly clear. Removing the surface starch prevents the dal from going foamy.

7. 7

   Prepare the onion: Take 1 medium onion. Peel and chop into fine 5mm dice.

8. 8

   Prepare the garlic: Take 3 garlic cloves. Crush, peel and mince finely.

9. 9

   Prepare the green chillies: Take 2 fresh green chillies. Slit lengthwise and chop. The fermented dal needs the heat to balance the umami depth.

10. 10

    Cook the lentils first: Place the washed lentils in a heavy pot with 3 cups water and 1 tsp turmeric powder. Bring to a boil over medium-high heat.

11. 11

    Skim the foam: As the dal comes to a boil, white foam will rise to the surface. Skim it off with a spoon and discard.

12. 12

    Simmer to soft: Reduce heat to medium-low. Simmer uncovered for 18-20 minutes, stirring every 5 minutes, until the dal is fully soft. The dal should look creamy with the lentils mostly broken down.

13. 13

    Mash gently: Use the back of a wooden spoon to lightly mash the dal against the sides of the pot. The texture should be smooth but with some character. Set aside in the pot, keeping warm on lowest heat.

14. 14

    Heat the mustard oil: Pour 2 tbsp mustard oil into a wide pan or kadhai over medium-high heat. Heat for 30-45 seconds until just smoking, to remove the raw bitter edge.

15. 15

    Fry the onion: Reduce heat to medium. Add the chopped onion. Stir-fry for 6-7 minutes until golden brown. Take your time — well-browned onion balances the strong umami of the axoni.

16. 16

    Add the garlic: Add the minced garlic. Stir for 1 minute until fragrant.

17. 17

    The critical axoni step: Add the 1/2 cup axoni to the pan. Use a flat spatula to break it up and stir-fry for 3 minutes on medium heat. The axoni will soften, melt slightly into the oil, and release its powerful fermented aroma. The kitchen will fill with an intensely savoury smell — this is normal and good.

18. 18

    Add dry spices: Sprinkle in 1 tsp turmeric powder. Stir for 30 seconds.

19. 19

    Combine with the dal: Tip the cooked dal into the axoni pan along with all its cooking liquid. Stir well. Add the green chillies. Add 1/2 cup hot water if the mixture is very thick.

20. 20

    The critical taste check before salt: Now this is essential — taste the dal before adding any salt. Axoni is already significantly salty from fermentation; adding salt blindly will produce an inedibly salty dal. Take a clean spoon, taste, and only add salt if needed (often 1/4 tsp or none at all).

21. 21

    Simmer to develop: Reduce heat to medium-low. Simmer uncovered for 10 minutes, stirring every 2 minutes. The flavours will meld together and the colour will deepen. The dal will develop the rich, deeply savoury character that defines this dish.

22. 22

    Final flavour check: Taste again after simmering. The dal should hit you with multiple flavours — earthy lentils, deeply savoury fermented soybean, sweet caramelised onion, gentle chilli warmth. Adjust salt only if absolutely needed.

23. 23

    Serve with rice: Serve hot over plain steamed rice — the dal is too intensely flavoured to pair with anything else. The rice is essential to balance the strong umami. Some Assamese homes also pair this with fried fish or boiled potatoes (aloo pitika, recipe id 1205) on the side.

    A cultural note: Mah Korai Axoni Dal is a beloved everyday food in many Assamese tribal communities, including the Sumi and Lotha Naga groups whose food traditions extended into upper Assam. The fermented soybean adds B vitamins, probiotic benefits, and a flavour profile that has no Western equivalent — try it once and you will understand why the cuisines of Northeast India deserve far more international recognition.
