Corn and Bean Stew Arunachal

Method

1. 1

   About Corn and Bean Stew: This three-protein stew — sweet corn, black beans and fermented soybean — is the cold-season energy staple of Arunachali farming communities, particularly the Adi and Galo highland peoples. It combines three plant proteins for a complete amino acid profile, providing sustained energy needed for cold mountain weather. The fermented soybean (pehak) gives the dish its distinctive umami depth.

2. 2

   Understand pehak: Pehak (also called kinema in Sikkim or akhuni in Nagaland) is the Northeast Indian family of fermented soybean pastes. It has a strong fermented aroma and provides intense umami flavour. Sold at Northeast Indian groceries.

3. 3

   If pehak is unavailable: Substitute with 1 tbsp Korean doenjang or Japanese miso paste — both deliver similar umami fermented soybean character. The flavour profile differs slightly but the dish works.

4. 4

   Measure carefully: Use only 1 tbsp pehak — fermented soybean is intensely flavoured, a little goes a long way.

5. 5

   Choose corn kernels: Use 1 cup of fresh or frozen sweet corn kernels. Fresh corn cut from the cob in summer is the most authentic. Frozen kernels can go in directly without thawing. Avoid canned corn — it has been over-cooked and lacks character.

6. 6

   Choose black beans: Use 1 cup of cooked black beans. To cook from dried, soak 1/2 cup dried black beans overnight, then drain and pressure cook with 2 cups water for 4-5 whistles plus 5 minutes on low heat.

7. 7

   If using canned black beans: Drain a 400g can and rinse thoroughly.

8. 8

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

9. 9

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

10. 10

    Prepare the green chilli: Take 1 fresh green chilli. Slit lengthwise and chop.

11. 11

    Use a wide pan: Use a wide kadhai or heavy frying pan. The stew has substantial volume of solids.

12. 12

    Heat the oil: Pour 2 tbsp neutral cooking oil into the pan over medium-high heat. Heat for 30 seconds until shimmering. Mustard oil works as substitute for more pungent flavour.

13. 13

    Fry the onion: Reduce heat to medium. Add the chopped onion. Stir-fry for 4-5 minutes until soft and just turning golden at the edges.

14. 14

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

15. 15

    The critical pehak step: Add the 1 tbsp pehak (fermented soybean paste) to the pan. Use a spatula to break it up as it hits the hot oil. Stir constantly for 2 minutes — the pehak will melt into the oil and release its powerful fermented aroma. The kitchen will fill with a deeply savoury smell. Do not let it burn — it can scorch quickly.

16. 16

    Add the cooked beans and corn: Add the cooked black beans, sweet corn kernels, 1 tsp turmeric powder and the green chilli. Stir well to combine.

17. 17

    Fry briefly: Stir-fry on medium heat for 2 minutes. The vegetables should be coated with the spiced oil.

18. 18

    Add water: Pour in 2 cups of hot water. The water should just cover the vegetables.

19. 19

    Bring to a boil: Increase heat to medium-high to bring to a boil. Then reduce to medium-low.

20. 20

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

21. 21

    Simmer to thicken: Simmer uncovered for 20 minutes, stirring every 3-4 minutes. The mixture will gradually thicken as the bean starches release into the liquid. The stew should look thick — like a hearty soup.

22. 22

    Mash some beans for body: Use the back of a wooden spoon to crush about a quarter of the beans against the sides of the pan. This naturally thickens the stew without flour or thickener.

23. 23

    Final consistency check: The stew should be thick enough to coat a spoon — pourable but substantial. If too thin, simmer 2-3 more minutes uncovered. If too thick, stir in 1/4 cup hot water.

24. 24

    Final flavour adjustment: Taste again after simmering. The stew should hit you with multiple flavours — sweet corn, earthy black beans, deep fermented umami, gentle chilli warmth. Adjust by adding more chilli (for heat) or a tiny pinch of sugar (to balance saltiness from the pehak).

25. 25

    Serve over rice: Serve hot ladled over plain steamed rice — the most traditional Arunachali pairing. The thick stew is meant to mix into the rice, creating a complete one-bowl meal.

26. 26

    A nutritional note: This dish is exceptionally complete in nutrition — corn provides carbohydrates and B vitamins, black beans provide protein and fibre, fermented soybean provides B12 and probiotics. The combination is almost a textbook example of plant-based complete protein and nutrient-dense eating.

27. 27

    Leftover storage: Stored in the fridge in an airtight container, this stew keeps for 3-4 days and improves overnight as flavours deepen. Reheat gently on the stovetop with a splash of water if too thick.
