Directions

1. 1Stir together 1 1/2 teaspoons garam masala, 1 1/2 teaspoons kosher salt, and the black pepper in a small bowl. Pat-dry the chicken with paper towels and evenly season with the spice mixture. You can cook the chicken right away or dry-brine by arranging on a rack set in a rimmed baking sheet and refrigerate uncovered for up to 24 hours.
2. 2Place the rice in a medium bowl. Cover with cool tap water, use your hand to gently agitate the grains, and drain. Repeat at least 2 more times until water runs clear enough to see your hand through it. Cover with cool tap water and set aside to soak while you prepare the rest of the dish (this helps the rice cook evenly).
3. 3In a small food processor or blender, puree the onion, garlic, ginger, and yogurt until smooth, adding a splash of water if needed. If you’re using the saffron: Crush the threads between your fingers and steep in 1 tablespoon of hot water in a small bowl.
4. 4In a medium cast-iron pan or high-sided skillet, heat the oil over medium. Add chicken, skin side-down. Cook until the skin is deeply golden brown, the fat has rendered, and the chicken releases from the pan, 12 to 15 minutes. Transfer to a plate.
5. 5Add potatoes to the residual schmaltzy oil. Sear over medium-high until lightly golden brown on all sides, 3 to 5 minutes. Transfer the potatoes to a plate with a slotted spoon, leaving as much fat behind as possible, and season them generously with salt.
6. 6Add the onion puree, remaining 1 1/2 teaspoons garam masala, and a big pinch of salt to the the skillet. Cook over medium-high, stirring occasionally at first and more frequently as it cooks down, until the puree is thick, caramelized, and the fat has broken out, 5 to 7 minutes.
7. 7Drain the rice. Add the rice, potatoes, and prunes to the skillet, and stir to combine. Add 2 cups of water, season with salt until the cooking liquid tastes as seasoned as you want your final dish to taste, and bring to a boil over medium-high heat. Nestle the chicken thighs into the rice, pouring over any juices that accumulated while the chicken sat. Reduce the heat to medium-low, drizzle the saffron tea and threads over the rice, simmer gently until rice has absorbed all the water and everything is cooked through and tender, 25 to 30 minutes. (If the water evaporates before the rice has cooked through, add a few splashes of water across the rice and continue cooking.)
8. 8Remove from heat and rest for 10 minutes before serving with extra yogurt, radishes, and cucumbers alongside.
