How do you bake macaroni and cheese?

Buy the right cheese! And cook it slowly. Re cheese - some will brown better than others ... not sure why. Kraft 'Cheese' (don't know where you are in the world?) will brown really well but then it's not really cheese is it? In fact in Australia the packaging for this says 'Kraft Singles' as they're not allowed to call it cheese! Anyway you wouldn't use Kraft to make macaroni. Also cook then stick under grill to do browning.
