Preheat oven to 400 degrees F.
Heat canola oil in a large Dutch oven or a tagine over high heat. Season chicken with salt and pepper on both sides and place in the hot pan, skin side down, in batches if needed; cook until golden brown. Turn the thighs over and cook for 2 minutes longer. Remove chicken to a plate.
Remove all but 2 tablespoons of the oil from the pan then add the olive oil and heat over medium heat. Add the onions and cook until soft. Add the garlic and cook for 30 seconds. Add the ras al-hanut and cook another 30 seconds. Add the saffron with the soaking liquid, cinnamon stick, tomatoes, chickpeas, and apricots and bring to a simmer. Nestle the chicken into the mixture and bring to a simmer. Cover and cook on the stovetop or in the oven for 35 to 40 minutes or until the chicken is tender. Do not remove the lid to check on the chicken until this time. Garnish each serving with a dollop of Harissa Sauce, parsley and cilantro.
1/2 cup creme fraiche
1 tablespoon harissa*
*Cook's Note: Harissa is a fiery paste of chiles, garlic, and spices. It is available at specialty markets.
