Bihari Baingan Masala

Method

1. 1

   About Bihari Baingan Masala: Stuffed baby eggplant is the showpiece vegetarian dish of Bihari kitchens — each small eggplant slit and filled with a freshly ground spice paste, then slow-cooked until completely tender. The Bihari version uses mustard oil and amchur for the distinctive sweet-sour-pungent flavour profile. It is made for special meals when impressing guests matters.

2. 2

   Choose the right baby eggplants: Use 8 small purple baby eggplants — the Indian variety, about 6-8cm long and 4cm wide. The skin should be glossy purple-black, the body firm, and the green stem still attached. Avoid soft, wrinkled or seedy ones; mature eggplants taste bitter and the seeds turn unpleasant when cooked.

3. 3

   Wash and prepare the eggplants: Wash thoroughly under cold running water. Pat dry with a kitchen towel. Trim only the very tip of the bottom — leave the stems on, as they hold the eggplants together during cooking.

4. 4

   Make the cross-cut: Stand each eggplant upright with the stem at the top. Using a sharp knife, make a deep cross-cut from the bottom upward — going up about 80% of the way to the stem, but not cutting through. The eggplant should remain in one piece, with four flaps that can be opened up like a flower. Drop each prepared eggplant into a bowl of cold salted water as you go to prevent browning.

5. 5

   Make the spice paste: In a small grinder or mortar combine 1 tsp cumin seeds, 1 tsp coriander seeds, 1 tsp red chilli powder, 1/2 tsp turmeric, 1/2 tsp amchur (dried mango powder), 2 garlic cloves and salt to taste — about 1 tsp. Grind to a thick coarse paste, adding 1-2 tbsp water if needed to bring it together. The paste should hold its shape when scooped.

6. 6

   Stuff the eggplants: Drain the eggplants and pat dry. Open up each cross-cut and use your fingers or a small spoon to stuff about 1.5 tsp of spice paste deep into each eggplant. Press the cuts closed gently to seal in the filling. Some paste will remain on the outside; that is fine and adds extra flavour to the gravy.

7. 7

   Reserve any leftover paste: If you have any spice paste left over, save it — it will go into the gravy at the end.

8. 8

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

9. 9

   Prepare the tomatoes: Take 2 medium tomatoes. Chop finely or, even better, blend to a smooth puree.

10. 10

    Heat the mustard oil correctly: Pour 2 tbsp mustard oil into a wide heavy-bottomed pan or kadhai over medium-high heat. Heat for about 1 minute until the oil just begins to smoke and the harsh raw smell mellows. Skipping this step leaves the dish tasting harsh.

11. 11

    Fry the stuffed eggplants gently: Reduce heat to medium. Place the stuffed eggplants in the pan in a single layer. Fry for 8-10 minutes, turning very gently every 2 minutes with two spoons (so the stuffing does not fall out). The skin should turn slightly wrinkled and faintly golden on all sides. Lift the eggplants out carefully with a slotted spoon and set aside.

12. 12

    Fry the onion: To the same oil add the chopped onion. Stir-fry for 6-7 minutes until deep golden brown. Take your time — well-browned onion is the foundation of the gravy.

13. 13

    Add the tomatoes and remaining paste: Add the chopped or pureed tomatoes to the pan along with any leftover spice paste. Stir well. Cook for 8 minutes on medium heat, stirring every 2 minutes, until the tomatoes have fully broken down into a thick paste and oil starts to separate at the edges.

14. 14

    Add water for the gravy: Pour in 1/2 cup hot water. Stir to form a thick gravy. Bring to a gentle simmer. Taste and adjust salt — about 1/4 tsp may be needed since the eggplants already carry the salted spice paste.

15. 15

    Return the eggplants gently: Lower the fried eggplants back into the gravy with a spoon, in a single layer. Spoon some gravy over the top of each one.

16. 16

    Cover and slow-cook: Cover the pan with a tight-fitting lid. Reduce heat to low. Cook for 18-20 minutes, gently turning the eggplants once halfway through using two spoons. Do not stir — gentle turning preserves the shape and stuffing.

17. 17

    Check doneness: Pierce one eggplant with a knife — it should slide in with no resistance and the eggplant should look glossy, soft and dark. The gravy should have thickened to coat the back of a spoon.

18. 18

    Adjust and finish: If the gravy looks watery, simmer uncovered for 2-3 more minutes. If too thick, add 2-3 tbsp hot water. The final dish should have eggplants nestled in a thick, glossy, dark spice gravy.

19. 19

    Garnish and serve: Sprinkle 2 tbsp finely chopped fresh coriander over the top. Serve hot with hot rotis, paratha, puri or alongside dal and rice. Bihari Baingan Masala tastes even better the next day after the eggplants have soaked in the gravy overnight — store in the fridge and reheat gently before serving.
