Boil the kettle and preheat the oven to 160 C (320F) degrees.
Take your chicken thighs and, using a pair of scissors, trim off any excess fat. Sprinkle the skin side with salt.
Take a good pinch of saffron threads and place in a teacup. Half fill the teacup or small mug with water from the kettle which has come off the boil and leave to infuse.
Pour a generous slug (a couple of tablespoons) of olive oil into an ovenproof shallow casserole dish (one which comes with a lid).
Heat to a medium heat and gently fry the peeled whole garlic cloves on each side until pale golden. Remove and set aside. They have a sweet, mild flavour when cooked whole this way, not at all strong.
Turn the heat to a high temperature and fry the chicken thighs to seal, skin side down until pale golden, turn and seal on the other side.
Turn so that the skin side is up again. Turn the heat down to a medium heat. Pour the white wine in to the pan. It will spit and sizzle. Shake the pan so that the oil and white wine emulsify.
Spoon the infused saffron and water over the thighs, adding the threads too.
Return the golden garlic cloves to the pan.
Place the ovenproof lid or tin foil on the pan and cook in the oven for 45 minutes, until the chicken comes away from the bone easily.
Half way through cooking add the green beans.
Serve the saffron chicken in its oven proof dish with all the lovely, creamy juices.
