My 6.5 pound prime rib only half hour late

Black salt brined for 48 hours. Over night uncovered in the fridge. Smothered with compose butter with herbs from my garden and garlic. Baked at 225 for 32.5 mins a pound with water and rosemary under the pan. 20 min rest and then 8 minutes at 550 for the sear. Damn it was good
