-(Grated) Fill a large deep pot 0.75 full with water. Add salt and bring to a rolling boil. Add pasta slowly, without breaking the boil. Cook 10 minutes. Place a colander in sink and turn pasta into it. Rinse under hot running water, allowing the water to drain through the spaghetti. Heat the butter in a small saucepan to a honey brown. Watch it carefully for these minutes; it burns quickly and suddenly. Return spaghetti to large pot and dribble hot butter over it. Sprinkle with half the cheese and toss gently to mix. Transfer to a large ovenproof platter, sprinkle top with more cheese and bake for 10 minutes at 180ºC . Serve hot.
