Bihari Kathal Curry

Method

1. 1

   About Bihari Kathal Curry: Raw jackfruit curry is the prestigious vegetarian of Bihar — its meaty fibrous texture is so satisfying that meat-eaters often prefer it. The dish is sometimes called "vegetarian mutton" because the texture of properly cooked raw jackfruit genuinely mimics slow-cooked meat. It is a celebration dish for vegetarian Bihari meals, suitable for festivals, gatherings, and Sunday family lunches.

2. 2

   Understand raw jackfruit: Use 500g of raw (green) jackfruit. The fruit is large, oval, with a rough green spiky exterior. Available at Indian groceries and specialty Asian markets in South Asian regions, particularly during summer (jackfruit season). Pre-cleaned cubed raw jackfruit (in cans or vacuum-sealed packs) is also widely available — much easier for home cooks.

3. 3

   If using fresh raw jackfruit: Be prepared for a sticky job. Raw jackfruit produces a sticky white sap that coats everything it touches.

4. 4

   The critical sap protection: Oil your hands generously with neutral oil before handling fresh raw jackfruit. The oil prevents the sap from sticking to your skin. Also oil your knife — the sap will quickly coat the blade and make cutting difficult.

5. 5

   If using canned raw jackfruit: Drain and rinse thoroughly. The canned version is pre-cooked, so simmer time is reduced.

6. 6

   Cleaning fresh jackfruit: Cut the fruit in half. Remove the central core (it is too fibrous to eat). Cut the rest into 3cm cubes, removing any large seeds.

7. 7

   Prepare the onions: Take 2 medium onions. Peel and finely chop into 5mm dice.

8. 8

   Prepare the garlic: Take 4 garlic cloves. Crush, peel and mince finely.

9. 9

   Prepare the ginger: Take a 1-inch piece of fresh ginger. Peel and grate finely.

10. 10

    Prepare the tomatoes: Take 2 medium tomatoes. Chop into fine 5mm dice.

11. 11

    Use a heavy pot with tight lid: Use a heavy-bottomed Dutch oven, large kadhai with lid, or thick-bottomed casserole.

12. 12

    Heat the mustard oil correctly: Pour 3 tbsp mustard oil into the pot over medium-high heat. Heat for 1-2 minutes until smoking heavily.

13. 13

    The critical jackfruit pre-fry: Add the cubed jackfruit pieces to the smoking-hot oil. Sear for 5-6 minutes, stirring every 90 seconds, until lightly golden on most sides.

14. 14

    Why pre-fry matters: The pre-fry develops the meaty character that makes this dish distinctive. Skipping this step produces a softer, less interesting curry.

15. 15

    Lift the jackfruit out: Use a slotted spoon to remove the fried jackfruit pieces. Set aside on a plate.

16. 16

    Fry the onions: Reduce heat to medium. Add the chopped onions. Stir-fry for 8-10 minutes, stirring often, until deep golden brown.

17. 17

    Add ginger and garlic: Add the minced garlic and grated ginger. Stir for 1-2 minutes until fragrant.

18. 18

    Add the tomatoes: Tip in the chopped tomatoes. Cook on medium heat for 6-8 minutes, stirring every 2 minutes, until the tomatoes have completely broken down into a thick paste and oil starts to separate at the edges.

19. 19

    Add dry spices: Sprinkle in 1 tsp turmeric powder and 1 tsp red chilli powder. Stir for 30 seconds — the masala will turn a beautiful rust-red colour.

20. 20

    Return the jackfruit: Add the fried jackfruit pieces back to the pot. Stir gently to coat with the masala.

21. 21

    Add water: Pour in 1 cup of hot water. Add salt to taste — about 3/4 tsp.

22. 22

    The slow simmer: Bring to a gentle simmer. Reduce heat to medium-low. Cover the pot. Cook for 30 minutes, lifting the lid every 10 minutes to gently stir and check the moisture.

23. 23

    Watch the moisture: The braising liquid should always be present. Add 2-3 tbsp hot water if it gets too dry.

24. 24

    Check doneness at 30 minutes: Pierce a piece with a fork — it should slide in with no resistance, and the jackfruit should pull apart easily into stringy fibres. The texture is meaty and tender — this is when the dish is properly done.

25. 25

    If still firm: Cover and simmer 5-10 more minutes. Some jackfruit takes longer than others depending on age and variety.

26. 26

    Uncover and reduce: Remove the lid. Increase heat to medium. Stir gently for 5 minutes, allowing the gravy to reduce to a thick clinging consistency.

27. 27

    Finish with garam masala: Sprinkle in 1 tsp garam masala. Stir gently to combine. Garam masala goes in at the end so its aroma is preserved.

28. 28

    Final flavour check: Taste a piece of jackfruit with gravy. The dish should hit you with multiple flavours — meaty fibrous jackfruit, sweet caramelised onion, tangy tomato, warm masala, gentle chilli, fragrant garam masala, pungent mustard oil. The texture should genuinely remind you of slow-cooked meat.

29. 29

    Garnish: Switch off the heat. Sprinkle 2 tbsp finely chopped fresh coriander over the top.

30. 30

    Serve with rice or rotis: The traditional Bihari pairing is hot soft rotis or paratha. The meaty jackfruit pairs beautifully with bread. Steamed rice also works well.

31. 31

    For a complete vegetarian feast: Pair with a dal (Tadka or Palak), a small bowl of yogurt, and a sweet to finish. The complete meal represents Bihari vegetarian cooking at its finest.

32. 32

    Serving tip: Tell guests this is a vegetable dish before they try it. Many people are surprised that the meaty texture comes from a fruit. The reveal is part of the experience.

33. 33

    A cultural note: Raw jackfruit cooking is found across Bihar, West Bengal, Odisha, and Kerala — each region with its own version. The Bihari version's use of mustard oil and the deep frying-then-braising technique distinguishes it from the Bengali (which uses panch phoron and mustard paste) and Kerala (which uses coconut milk and curry leaves) versions.

34. 34

    A seasonal note: Raw jackfruit is at peak availability in summer (April-July). Outside these months, the dish is harder to make from fresh fruit but remains possible with canned or frozen jackfruit.

35. 35

    Leftover storage: Stored in the fridge in an airtight container, kathal curry keeps for 3-4 days and tastes even better the next day after the flavours have deepened. The jackfruit absorbs more masala overnight, becoming richer. Reheat gently on the stovetop with a splash of water if too thick.
