Kalam Polo (کلم پلو) — Persian Cabbage Rice

• 500 gBasmati rice (rinsed until water runs mostly clear)
• 2400 mlWater (for parboiling rice (plus extra for soaking raisins if needed))
• 18 gSalt (for salting parboil water)
• 700 gRed cabbage (cored and finely shredded (about 8–10 mm wide))
• 75 mlOlive oil (divided)
• 120 gRaisins (dark or golden; rinsed)
• 2 gBlack pepper (freshly ground)
• 3 gTurmeric (optional but traditional for color and warmth)
• 1.5 gGround cinnamon (optional, complements raisins)
• 30 mlBrewed saffron water (optional; made from 0.2 g saffron steeped in 30 ml hot water)
• 120 gPlain yogurt (optional; for yogurt tahdig)
• 1 pcEgg yolk (optional; for sturdier yogurt tahdig)

Instructions

1. 1

   Rinse the basmati rice in several changes of cool water until the water is mostly clear. Cover with fresh water and let it soak 30 minutes at room temperature to help the grains elongate. Meanwhile, shred the red cabbage finely and rinse the raisins; if very dry, soak raisins in warm water 10 minutes, then drain well.

2. 2

   Bring 2400 ml water to a rolling boil in a large pot. Add 18 g salt, then add the soaked, drained rice. Boil 6–8 minutes, stirring gently once or twice, until the grains are tender on the outside but still firm in the center. Drain immediately in a colander and rinse briefly with cool water to stop cooking.

3. 3

   Heat 45 ml olive oil in a wide skillet over medium-high heat. Add shredded red cabbage and sauté 8 minutes, tossing often, until it softens and turns glossy. Season with 4 g salt, 2 g black pepper, turmeric, and cinnamon (if using). Reduce heat to medium and cook 10–12 minutes more until tender but not mushy.

4. 4

   Push cabbage to the edges of the skillet and add the remaining 30 ml olive oil to the center. Add raisins and sauté 2–3 minutes until plump and fragrant, then toss through the cabbage. Taste and adjust seasoning; the mixture should be savory with a gentle sweetness. Remove from heat and let cool 5 minutes for easier layering.

5. 5

   For a yogurt tahdig (optional), mix yogurt, egg yolk, and 30 ml olive oil in a bowl until smooth. Add 150 g of the drained parboiled rice and stir to coat. Set a heavy-bottomed nonstick pot over medium heat, add the yogurt-rice mixture, and press into an even layer about 1–1.5 cm thick.

6. 6

   Layer the remaining rice and cabbage mixture in the pot: add a third of the rice, then half the cabbage-raisin mixture, repeating and finishing with rice on top. Drizzle saffron water (if using) over the surface. Use the handle of a spoon to poke 5–6 holes down to the bottom to vent steam.

7. 7

   Wrap the pot lid in a clean kitchen towel and cover tightly to catch condensation. Cook over medium heat for 8 minutes to build steam, then reduce to low and steam 40–45 minutes. The rice should smell toasted and the sides should look dry. Rest off heat 10 minutes before unmolding.

8. 8

   To serve, loosen the edges with a thin spatula. Place a platter over the pot and invert confidently to release the rice with tahdig. If it sticks, return to low heat 2–3 minutes to loosen. Alternatively, spoon rice onto a platter and break the tahdig into pieces to serve alongside.
