• 16 ozBasmati rice (Rinsed until water runs mostly clear)
• 18 gFine salt (For soaking and seasoning)
• 10.5 cupWater (For boiling rice)
• ¼ cupVegetable oil (Plus extra 10 ml for greasing the pan)
• 10.5 ozStrained yogurt (Thick Greek-style or Persian mast-e chakkideh)
• 4Egg yolks (Large yolks)
• 1 tspPersian saffron threads (Finely crushed)
• ¼ cupHot water (For blooming saffron)
• 1 tspGround turmeric (For warmth and color)
• 1⅛ lbChicken thighs, boneless skinless (Cut into 3 cm pieces)
• 1⅛ lbLamb shoulder, boneless (Cut into 2 cm pieces)
• 5.3 ozOnion (Thinly sliced)
• 2⅛ ozBarberries (zereshk) (Rinsed quickly and drained)
• 1 tbspBloomed saffron water (From the bloomed saffron mixture)

Instructions

1. 1

   Bloom the saffron by stirring the crushed saffron threads into 60 ml hot water, then let it stand for 10 minutes to deepen in color. Reserve 15 ml of this saffron water for the barberries and keep the rest for the tahchin batter.

2. 2

   Rinse the basmati rice 4–5 times until the water runs mostly clear, then soak it in plenty of water with 12 g of the salt for 20 minutes. Soaking helps the grains elongate and reduces breakage during parboiling.

3. 3

   Prepare the filling using either chicken or lamb, not both, for a clean classic tahchin layer. Heat 15 ml oil in a pan over medium heat, sauté the sliced onion for 6–8 minutes until soft and lightly golden, then add the meat, 1 tsp turmeric, and 6 g salt and cook for 3 minutes to coat and lightly sear.

4. 4

   Add 200 ml water to the pan, cover, and simmer until tender: 18–22 minutes for chicken thighs or 45–60 minutes for lamb shoulder, stirring once or twice. When done, uncover and reduce any excess liquid until the pan is nearly dry, because watery filling can soften the tahdig and prevent a crisp crust.

5. 5

   Parboil the rice by bringing 2500 ml water to a rolling boil in a large pot and adding the remaining 6 g salt. Drain the soaked rice, add it to the boiling water, and boil 6–7 minutes until the grains are softened on the outside but still firm in the center, then drain thoroughly in a colander.

6. 6

   Make the tahchin batter by whisking the strained yogurt and egg yolks until smooth and glossy, then whisk in the turmeric and most of the bloomed saffron water (keep the reserved 15 ml aside). Fold in about two-thirds of the drained rice gently so the grains are well-coated but not crushed, creating the saffron-yogurt matrix that bakes into a sliceable cake.

7. 7

   Prepare the barberries by heating 10 ml oil in a small pan over low heat and sautéing the rinsed barberries for 60–90 seconds, just until they plump and shine. Stir in the reserved 15 ml saffron water, then remove from heat immediately to prevent bitterness from overcooking.

8. 8

   Assemble the tahchin in a nonstick pot or a 24 cm nonstick springform pan for easy unmolding. Grease the base and sides with 10 ml oil, then spread half of the saffron-coated rice mixture firmly into the bottom, pressing to eliminate air pockets that can cause cracking.

9. 9

   Add the cooked chicken or lamb in an even layer, keeping it about 1 cm away from the edges so the crust can form continuously. Sprinkle half of the barberries over the meat, then cover with the remaining plain drained rice (the uncoated third) to create a lighter top layer and a more dramatic color contrast when sliced.

10. 10

    Drizzle the remaining 60 ml vegetable oil evenly over the top so heat conducts and the crust browns reliably. Cover tightly with a lid wrapped in a clean towel (to catch steam), then cook on low heat for 60 minutes in a pot, or bake at 190°C for 55–65 minutes until the sides are deeply golden and the aroma is nutty and saffron-forward.

11. 11

    Rest the tahchin for 10 minutes off heat so the crust sets and releases more cleanly. Invert onto a platter in one confident motion, then top with the remaining barberries and slice with a sharp knife, wiping between cuts for clean layers.
