Nagaland Naga Dal Fermented Bamboo Black Gram

Method

1. 1

   Pressure cook the black gram: Drain soaked black gram. Pressure cook with 4 cups water and turmeric for 12 to 15 whistles until completely soft.

2. 2

   Prepare fermented bamboo shoot: If using fermented bamboo, drain and rinse. Cut into thin strips. The sourness of fermented bamboo is the key — it adds a tang that distinguishes this dal from plains preparations.

3. 3

   Heat mustard oil until smoking: Heat 3 tbsp mustard oil until smoking. Reduce to medium.

4. 4

   Fry garlic: Add crushed garlic. Fry 30 seconds until golden.

5. 5

   Add cumin, dried chilli and asafoetida: Add cumin seeds — crackle. Add dried red chilli and asafoetida. Stir 15 seconds.

6. 6

   Cook onion: Add finely chopped onion. Cook 8 minutes until golden.

7. 7

   Add ginger: Add ginger paste. Stir 1 minute.

8. 8

   Add fermented bamboo shoot: Add the fermented bamboo shoot strips. Stir and cook 3 minutes — the sour fermented bamboo will release its characteristic tangy aroma.

9. 9

   Combine with dal: Pour the cooked black gram dal into the pan. Add salt. Stir well. Simmer on medium-low heat for 10 minutes until the bamboo shoot flavour infuses through the dal.

10. 10

    Serve: Scatter spring onions. Serve with steamed rice.

    Note: Fermented bamboo shoot (called bas tenga in Assam and similarly fermented in Nagaland) is a key souring and flavouring ingredient of the northeast region. In Nagaland, bamboo shoots are fermented in sealed bamboo tubes for several weeks, producing a sour, pungent ingredient used in dals, meat preparations and soups. The sourness of fermented bamboo is distinct from tamarind or kokum — more complex and earthy.
