Tahchin (ته چین) — Persian Saffron Yogurt Rice with Crispy Crust

• 500 gBasmati rice (rinsed until water runs mostly clear)
• 3000 mlWater (for parboiling rice)
• 18 gFine sea salt (divided: 12 g for boiling water, 6 g for yogurt mixture)
• 300 gPlain full-fat yogurt (unsweetened; Greek-style is fine)
• 3 largeEgg yolks (about 54 g total; yolks only for richer crust)
• 0.25 tspSaffron threads (about 0.5 g, finely crushed)
• 60 mlHot water (just off the boil, for blooming saffron)
• 1 tspBlack pepper (freshly ground)
• 75 mlVegetable oil (neutral oil such as sunflower or canola, divided)

Instructions

1. 1

   Rinse the rice in several changes of cool water until the water looks mostly clear, then drain well. Soak the rice in plenty of cool water with 6 g of the salt for 45 minutes. This improves grain separation and helps the crust set evenly later.

2. 2

   Bloom the saffron: crush the saffron threads to a fine powder, then stir with 60 ml hot water. Cover and let steep 10 minutes to fully extract color and aroma. Meanwhile, bring 3000 ml water to a rolling boil in a large pot and add the remaining 12 g salt.

3. 3

   Parboil the rice: drain the soaked rice and add it to the boiling salted water. Boil 6–8 minutes, stirring gently once or twice, until grains are softened on the outside but still firm in the center. Drain immediately in a fine colander and rinse briefly with 250 ml cool water to stop cooking.

4. 4

   Make the saffron-yogurt base: in a large bowl whisk yogurt, egg yolks, the bloomed saffron (all liquid), black pepper, and the remaining 6 g salt until completely smooth. Add about one-third of the warm drained rice and fold to coat, then fold in the remaining rice gently to avoid breaking grains.

5. 5

   Prepare the pot for tahdig: choose a 24–26 cm heavy nonstick or well-seasoned pot with a tight lid. Add 60 ml vegetable oil and swirl to coat the bottom and 2–3 cm up the sides. Spoon in the rice mixture, pressing firmly to eliminate air pockets and create an even, compact layer.

6. 6

   Steam-cook to set the crust: use the handle of a wooden spoon to poke 5–6 holes down to the bottom for steam channels. Drizzle 15 ml vegetable oil and 60 ml water over the rice. Cover the lid with a clean kitchen towel and tie it, then cook 10 minutes over medium heat until you hear gentle sizzling.

7. 7

   Finish on low heat: reduce to low and cook 55–60 minutes, keeping the lid closed. The goal is steady steam and gradual browning, not aggressive frying. If your stove runs hot, use a heat diffuser. The tahdig is ready when the aroma turns nutty and the sides look set and golden.

8. 8

   Unmold for a crown-like crust: turn off heat and rest the pot, covered, 10 minutes. Run a thin silicone spatula around the edge. Place a serving platter over the pot and invert confidently. Let the pot sit inverted 30 seconds, then lift; the golden crust should release in one piece or large sections.
