Instructions

1. 1

   Bloom the saffron: grind 0.5 tsp saffron threads to a fine powder, then pour 60 ml hot water (just off boiling) over it in a small cup. Cover and steep 20 minutes to develop a deep ruby-gold color. Meanwhile, wash the basmati rice 5–6 times until the water is mostly clear.

2. 2

   Soak the rice for fluffier grains: cover the washed rice with about 1.5 liters cool water and dissolve 10 g fine sea salt into it. Soak 45 minutes at room temperature. This step improves elongation and helps the rice steam evenly later, especially important for a layered polo.

3. 3

   Cook the curry chicken base: heat 30 ml neutral oil and 20 g butter in a wide skillet over medium heat. Add diced onion and sauté 8 minutes until translucent and lightly golden. Stir in garlic for 30 seconds, then add chicken, 2 tbsp curry powder, turmeric, black pepper, and 8 g salt.

4. 4

   Brown and braise: increase heat to medium-high and cook chicken 6–8 minutes, stirring, until edges color. Pour in 240 ml chicken stock, scrape the pan, then cover and simmer on low 12 minutes. Uncover, add sliced mushrooms, and cook 6 minutes until they release moisture and concentrate in flavor.

5. 5

   Finish the filling: stir in drained peas and cook 2 minutes just to heat through, keeping peas bright green. Taste and adjust salt if needed. The mixture should be moist but not soupy; if liquid remains, simmer uncovered 2–4 minutes until it lightly coats the chicken. Set aside, covered, to keep warm.

6. 6

   Parboil the rice: bring a large pot of water to a rolling boil (at least 3 liters). Add 20 g fine sea salt. Drain soaked rice and add to boiling water; boil 6–8 minutes until grains are softened on the outside but still firm in the center. Drain in a colander and rinse briefly with 250 ml cool water.

7. 7

   Prepare potato tahdig: in a 24–26 cm nonstick pot, heat 15 ml neutral oil over medium heat. Arrange potato slices in a tight, overlapping single layer. Mix 2 tbsp of the saffron solution with 2 tbsp water and drizzle evenly over potatoes. Cook 3 minutes until you hear a gentle sizzle.

8. 8

   Layer the polo: reduce heat to low. Add 1/3 of the parboiled rice over the potatoes, then spoon on half the chicken-mushroom-pea mixture. Repeat with another 1/3 rice and the remaining filling, finishing with the last 1/3 rice. Dot the top with the remaining 20 g butter in small pieces.

9. 9

   Steam to perfection: use the handle of a wooden spoon to poke 5–6 holes down to the bottom for steam channels. Wrap the lid with a clean kitchen towel and cover tightly. Steam 10 minutes on medium-low to build heat, then 45 minutes on low. Drizzle remaining saffron solution over the top in the last 10 minutes.

10. 10

    Unmold and serve: turn off heat and let the pot rest, covered, 10 minutes so the tahdig releases cleanly. Fluff the rice gently from the top, keeping layers intact. To unmold, place a platter over the pot and flip confidently. If needed, return to low heat 3–5 minutes to crisp further.
