Steep saffron in 1 tablespoon warm water in a small bowl for 10 minutes.
Season chicken with salt and pepper on both sides. Heat 2 tablespoons oil in a large pan or Dutch oven over medium-high heat. Sear chicken until browned on both sides. Remove and set aside.
Add shallots, serrano, and garlic, and saute until softened, about 3-4 minutes. Add tomato paste, cumin, paprika, coriander, and turmeric, and cook until tomato paste is caramelized, about 2 minutes. Add saffron with water, and rice, stirring to combine.
Add wine to the pan and bring it to a boil. Continue to simmer until almost all of the liquid has evaporated. Add back chicken along with chicken stock, cinnamon stick, salt, and pepper, and bring to a boil. Cover the pan, reduce heat to low, and continue to cook for 15-20 minutes or until rice is tender.
Remove cinnamon stick from the rice and fluff rice with a fork. Place dollops of labne on top and sprinkle toasted almonds, cilantro, and mint. Serve immediately.
