Persian Herb Rice with Potato Tahdig

1. 1Soak the rice. Place the rinsed rice in a bowl, cover with cold water by 2 inches, and soak for 30 minutes. Drain well. Soaking helps the grains lengthen rather than sulk into a clump.
2. 2BloomWarm a spice or seasoning briefly in fat or liquid to bring out more aroma and flavor. the saffron. Combine the crushed saffron and hot water in a small bowl. Set aside for 5 to 10 minutes while the rice cooks.
3. 3Parboil the rice. Bring the water and 1 1/2 tablespoons of the salt to a rolling boil in a large pot. Add the drained rice and cook, stirring once or twice, until the outside is tender but the center still has a firm bite, 5 to 7 minutes. Drain the rice in a fine-mesh colander and rinse briefly with cool water to stop cooking.
4. 4Season the herbs. In a large bowl, gently toss the parsley, cilantro, dill, scallions, and remaining 1/2 tablespoon salt for 2 to 3 minutes. Keep the herbs loose so they distribute through the rice rather than form one determined green boulder.
5. 5Build the potato tahdig. Choose a heavy 4- to 5-quart pot with a tight lid. Over 5 to 7 minutes, melt 3 tablespoons of the ghee over medium heat, swirling to coat the bottom. Arrange the potato slices in one overlapping layer across the bottom. Spoon about 1 cup of parboiled rice over the potatoes and drizzle with the saffron water.
6. 6Layer the rice and herbs. Over 5 to 8 minutes, add the remaining rice and herb mixture in alternating loose layers, finishing with rice. Shape the pile into a gentle mound and poke 5 or 6 holes to the bottom with the handle of a wooden spoon so steam can escape. Drizzle the remaining 1 tablespoon ghee over the top.
7. 7Steam until tender and crisp underneath. Wrap the pot lid in a clean kitchen towel, securing the ends well away from the burner, and cover the pot. Cook over medium heat for 5 minutes to start the crust, then reduce to low and steam until the rice is tender and the potatoes are deeply golden at the bottom, 35 to 40 minutes. Do not keep lifting the lid; the steam has a job.
8. 8Rest and unmold. Remove the pot from the heat and let it stand, covered, for 5 minutes. Loosen the edges with a thin spatula. Place a serving platter over the pot and carefully invert in one confident motion. Serve immediately while the tahdig is crisp.

Rice-only tahdig

Skip the potato. Mix 1 cup of parboiled rice with 1 tablespoon ghee and the saffron water, spread it across the pot bottom, then layer the remaining rice and herbs on top.

Lemon herb rice

Add 1 teaspoon finely grated lemon zest to the herb mixture before layering for a brighter finish.
