Instructions

1. 1

   Toast the walnuts to deepen flavor: spread on a tray and bake at 160°C/320°F for 10–12 minutes, stirring once, until fragrant but not dark. Cool completely. Meanwhile, pat duck pieces very dry, then season with 10 g salt, 2 g pepper, and 4 g turmeric, coating all sides evenly.

2. 2

   Render and brown the duck: heat a heavy pot over medium heat and add 30 mL vegetable oil. Place duck pieces skin-side down and cook 8–10 minutes until a good amount of fat renders and the skin turns golden. Flip and brown 4–6 minutes more. Transfer duck to a plate; keep 2 tablespoons rendered fat in the pot.

3. 3

   Build the base: reduce heat to medium-low, add the diced onion to the pot, and sauté 12–15 minutes until deeply golden and sweet, scraping up browned bits. Add a splash of water if it threatens to scorch. This slow onion step is key for a rounded, regal sauce rather than a sharp one.

4. 4

   Make the walnut sauce: grind cooled toasted walnuts to a fine meal in a processor. Transfer to a blender and blend with 700 mL hot water until very smooth and creamy, 1–2 minutes. Pour the walnut mixture into the pot with onions and simmer gently for 10 minutes, stirring often to prevent sticking.

5. 5

   Slow-braise: return duck pieces to the pot, nestling them into the walnut sauce. Add the remaining 500 mL water, bring to a gentle simmer, then cover and cook on low heat for 90 minutes. Keep the stew at a lazy bubble; stir every 15–20 minutes, especially along the bottom, to avoid scorching.

6. 6

   Prepare the eggplant while the stew cooks: sprinkle eggplant rounds with 6 g salt and rest 20 minutes to draw out bitterness. Rinse quickly and pat very dry. Pan-fry in 45 mL oil over medium heat 3–4 minutes per side until golden, or bake at 220°C/425°F for 20–25 minutes, flipping halfway.

7. 7

   Season and deepen color: after 90 minutes, stir in the sour pomegranate molasses (150 mL). Simmer uncovered 30–40 minutes to thicken and darken, stirring frequently. If the sauce becomes too thick, add 60–120 mL water. Taste and adjust with the remaining pepper and a small amount of extra molasses if needed.

8. 8

   Finish with herbs and serve: gently fold in mint, parsley, and cilantro and simmer 2 minutes to perfume the stew without dulling the herbs. Add fried or baked eggplant on top and warm 5 minutes. Rest off heat 10 minutes so the walnut oil rises slightly and the flavors round out before serving.
