• 1.5 lbChicken thighs, boneless skinless (cut into 4–5 cm pieces)
• 7.1 ozYellow onion (finely chopped)
• ⅜ cupVegetable oil (divided)
• ½ tspGround saffron (bloomed in hot water)
• ¼ cupHot water (for blooming saffron)
• 1 tspGround turmeric
• ½ tspGround black pepper
• 1½ cupWater (for braising; add more only if needed)
• 1⅓ lbEggplant (peeled in stripes and cut into 1.5 cm slices)
• 7¾ ozWhole milk yogurt (thick, unsweetened)
• 2Egg yolks
• 1.1 ozUnsalted butter (melted)
• 2½ ozDried barberries (zereshk) (picked over and rinsed quickly)

• 1.1 ozSlivered almonds (lightly toasted)

Instructions

1. 1

   Rinse the basmati rice in several changes of cool water until it runs mostly clear, then drain well. Dissolve 12 g of the salt in 1.5 liters of water and soak the rice for 30 minutes; this helps the grains elongate and cook evenly.

2. 2

   Bloom the saffron by stirring 0.5 tsp ground saffron into 60 ml hot water, then cover and set aside for at least 10 minutes. This step extracts maximum color and aroma so the rice perfumes the whole dish.

3. 3

   Cook the chicken: heat 30 ml vegetable oil in a pot over medium heat and sauté the chopped onion for 6–8 minutes until golden. Add chicken, turmeric, black pepper, and 6 g salt, then sear for 5–6 minutes, turning to lightly brown the pieces.

4. 4

   Add 350 ml water and 2 tbsp (about 30 ml) of the bloomed saffron water to the chicken pot, then bring to a gentle simmer. Cover and cook for 25–30 minutes until the chicken is tender and the liquid is mostly reduced; you want moist chicken, not a soupy stew.

5. 5

   Prepare the eggplant: sprinkle the slices with 6 g salt and rest for 20 minutes to draw out bitterness. Rinse quickly, pat very dry with towels, and keep them in a single layer so they fry rather than steam.

6. 6

   Fry the eggplant: heat 120 ml vegetable oil in a wide skillet over medium-high heat until shimmering. Fry eggplant in batches for 3–4 minutes per side until deeply golden, then drain on a rack or paper towels; add 15 ml more oil only if the pan becomes dry.

7. 7

   Parboil the rice: bring a large pot with 3 liters of water to a rolling boil and add the remaining 6 g salt. Drain the soaked rice, add it to the boiling water, and boil 6–7 minutes until the grains are tender on the outside but still firm in the center, then drain in a colander.

8. 8

   Make the tahdig base by whisking yogurt and egg yolks in a bowl until completely smooth. Stir in 2 tbsp (about 30 ml) of the bloomed saffron water to tint the mixture; this gives the crust its signature color and rich flavor.

9. 9

   Assemble the pot: warm 30 ml vegetable oil in a heavy, nonstick pot over medium heat for 1 minute. Pour in the saffron-yogurt mixture and spread it evenly, then add about 1/5 of the parboiled rice to cover the bottom in a gentle, even layer.

10. 10

    Layer the fillings: scatter half the chicken and half the fried eggplant over the rice, keeping a 1–2 cm border from the sides to protect the tahdig. Add another layer of rice, then repeat with remaining chicken and eggplant, finishing with the last layer of rice shaped into a small mound to help steam circulate.

11. 11

    Steam the polo: poke 5–6 holes down through the rice with the handle of a spoon to vent steam. Drizzle the melted butter and the remaining saffron water over the top, cover the lid with a clean towel, and steam 10 minutes over medium heat, then 45 minutes over low heat until fragrant and fully set.

12. 12

    Prepare the jeweled topping: in a small pan, warm 15 ml vegetable oil over low heat and add the rinsed barberries. Sauté for exactly 60–90 seconds, stir in the sugar, then immediately remove from heat to prevent burning; fold in the toasted pistachios and almonds.

13. 13

    Unmold and serve: rest the pot off heat for 5 minutes, then place a platter over the pot and invert confidently to release the tahdig. Garnish the rice with the barberry-nut mixture, and serve the crisp tahdig pieces alongside so everyone gets a share.
