I got the idea of the bed of salt from somewhere, but way older than 425F for two hours.
So what I found about beds of salt had you put the potatoes on the bed of salt and then cover it for the first bit of cooking time and then uncover it for the second bit of cooking time. Do you do that?
I recall that you were unimpressed with steam bake on the CSO for your baked potatoes.
