Saffron is very expensive, but it gives a wonderful flavor and is considered a brain healthy spice. If using saffron threads, soak them in a couple of tablespoons of hot water for at least 15 minutes prior to use. Mash the threads with the back of a spoon. If you have time, soak the threads for several hours and do not mash them.
This recipe is best if the chicken is marinated for a minimum of 2 hours, up to 24 hours.
