Start by cooking the rice; place the rice and boiling water in a large, heavy-based saucepan. Bring to the boil over a moderate heat, then cover with a lid and reduce to a simmer. Simmer for 12-15 minutes, then remove from the heat and reserve to one side, making sure you keep the lid on.
Heat the olive oil in a large frying pan over a moderate heat until hot. Season the chicken breasts, then sear until golden in colour all over. Reduce the heat and continue to cook the chicken breasts, turning occasionally, for 10 minutes.
Add the orange juice, pared zest of 1 orange and the saffron strands to the pan and allow the juice to reduce by three-quarters. Cook for another 5 minutes until the chicken breasts are cooked through with no pink showing and you have a syrup-like sauce.
Fluff the rice with a fork and reheat if necessary. Spoon into a serving dishes and pour over the soy sauce. Sit the chicken breasts on top, spooning the sauce on top of them. Serve immediately.
