Instructions

1. 1

   Rinse the basmati rice in several changes of cold water until the water runs mostly clear. Cover the rice with plenty of water, add 10 g of the salt, and soak for 30 minutes to help the grains elongate and cook evenly.

2. 2

   Crush the saffron threads to a fine powder, then pour 60 ml hot water over it and cover. Let it bloom for at least 15 minutes so the color and aroma fully develop, then set it aside for layering and tahdig.

3. 3

   Prepare the orange peel by placing the julienned peel in a small saucepan and covering with 300 ml water. Bring to a boil for 2 minutes, drain, and repeat this blanching process two more times with fresh 300 ml water each time to remove bitterness.

4. 4

   Make a light syrup by combining 120 g sugar with 120 ml water in the same saucepan and bringing it to a gentle simmer. Add the blanched orange peel and simmer for 8 minutes, then stir in the rose water and cardamom and cook 1 minute more before removing from the heat.

5. 5

   Melt 30 g of the butter in a skillet over low heat and add the drained barberries. Stir for 60–90 seconds until glossy and slightly plumped, then immediately remove from the heat to prevent scorching; barberries burn quickly and turn bitter.

6. 6

   In the same skillet, melt another 15 g butter and gently toast the drained slivered almonds for 2–3 minutes until fragrant. Stir in the cinnamon if using, then combine the almonds with the barberries and set the mixture aside for layering.

7. 7

   Bring 2500 ml water to a rolling boil in a large nonstick pot and add the remaining 8 g salt. Drain the soaked rice, add it to the boiling water, and boil for 6–8 minutes; the grains should be soft on the outside with a firm core when you bite one.

8. 8

   Drain the rice in a colander and rinse quickly with 200 ml cold water to stop the cooking and wash off excess surface starch. Let it drain for 5 minutes so steam escapes and the rice stays fluffy rather than clumpy.

9. 9

   Make the tahdig base by whisking the yogurt, egg yolk, 30 ml neutral oil, and 15 ml of the bloomed saffron in a bowl. Mix in 120 g of the parboiled rice until evenly coated, which helps create a cohesive, crisp crust.

10. 10

    Warm the pot over medium heat for 2 minutes, then spread the yogurt-rice mixture evenly across the bottom to form the tahdig layer. Pile the remaining rice on top in a gentle mound, poke 5–6 holes down to the bottom with the handle of a spoon, and drizzle 30 ml of the saffron water over the top for color.

11. 11

    Dot the top of the rice with the remaining 45 g butter cut into small pieces, then cover the lid with a clean kitchen towel and place it on the pot. Steam on medium heat for 10 minutes to build heat, then reduce to low and steam for 45 minutes until the rice is fully tender and aromatic.

12. 12

    Gently warm the candied orange peel in its syrup for 1–2 minutes so it loosens and becomes glossy, then drain it well so the rice does not turn wet. Fluff the rice with a spatula, then layer in the barberry-almond mixture and orange peel, reserving a small amount of each for garnish.

13. 13

    Transfer the mixed rice to a serving platter, keeping some white and some saffron-stained grains visible for a traditional marbled look. Loosen the tahdig by letting the pot rest off heat for 3 minutes, then invert or lift out the crust and serve it alongside the rice, garnished with pistachio slivers.
