Prime rib

My first. 10 lbs, bone in. Cooked at 175 for 6 hours until temp hit 128. Out of the oven for a rest with a light foil tent for 45 mins. Internal temp rose to 133.5 during the rest. Back in to oven on air fryer at 500 degrees for 6 mins. Exterior was blistered and delicious. Medium rare and just right. Served with homemade chimmichurri and horseradish sauces. Both were a hit.
