Bagara Baingan — Aubergine in Tamarind-Nut Gravy (بغارہ بینگن)

Ingredients

• 6 small round aubergines, Hyderabadi purple-white striped variety preferred; slit in a cross from the base, stem left intact
• For the nut-seed paste
• 3 tbsp raw peanuts, roasted and ground
• 2 tbsp sesame seeds, roasted and ground
• 2 tbsp dried coconut, roasted and ground
• For the sauce base
• 2 onions, sliced and fried to deep caramel for kanda paste
• 30 g tamarind, soaked and pulp extracted
• 2 tbsp neutral oil
• 1 tsp mustard seeds
• 1 tsp cumin seeds
• 1 tsp ground coriander
• ½ tsp ground turmeric
• 1 tsp red chilli powder
• to taste salt

Method

1. 1
   Dry-roast the peanuts, sesame seeds, and dried coconut separately in a heavy pan over medium heat until each is golden and fragrant, keeping them apart so each releases its oils at its own pace without scorching. Allow to cool, then grind together to a coarse-fine paste — not so fine that the paste dissolves into the sauce, not so coarse that it fails to integrate. The correctly ground paste will hold together in a rough, cohesive mass.
2. 2
   Fry the sliced onions in oil over low-medium heat, stirring frequently, until deeply caramelised and mahogany throughout, because only onions cooked this far will give the gravy its characteristic sweetness and body rather than a sharp, raw undertow. Grind or mash to a smooth kanda paste. The paste should be sweet, collapsed, and uniform — no raw-onion sharpness remaining.
3. 3
   Slit each aubergine from the base in a cross, keeping the stem fully intact so the aubergine remains in one piece and the sauce has a channel through which to reach the flesh. Fry the slit aubergines in oil — by deep-frying or sautéing — until the exterior is lightly firmed and the skin shows a slight colour, which gives the aubergine the structure to braise without collapsing. The skin should be set and no longer raw-looking.
4. 4
   Heat oil in a wide, heavy pan, add the mustard seeds and cumin seeds, and allow them to splutter so their volatile fragrance blooms into the oil and carries through the entire sauce. Add the kanda paste and stir for a minute over medium heat. Add the ground coriander, turmeric, and red chilli powder and cook the spice mixture briefly until the raw smell of the spices fades.
5. 5
   Add the tamarind pulp to the sauce base and cook it through over medium heat, stirring, until the sourness has rounded and the harshness of raw tamarind is gone — this is where the dish lives or dies, because tamarind cooked fully into the sauce at this stage becomes mellow and integrated, whereas tamarind added later will remain sharp and unincorporated, unbalancing the finished dish. The sauce should darken slightly and thicken at the edges.
6. 6
   Add the nut-seed paste to the tamarind sauce and stir to combine fully, then add sufficient water to achieve a thick, cohesive gravy. Cook over medium heat, stirring, until the raw peanut flavour has cooked out entirely, so the paste loses its heavy, bitter edge and the sauce smells roasted and rounded.
7. 7
   Nestle the par-fried aubergines into the sauce, pressing gently so the cross-cuts open and the sauce begins to enter the interior, since the slits you made at the start exist precisely to carry the tamarind-nut gravy to the centre of each aubergine rather than leaving it a bland core. Cover and braise over low heat, turning the aubergines occasionally, until they are fully tender and have absorbed the sauce completely. They should hold their shape; a knife should meet no resistance at the centre.
