How to make a prime rib in mushroom and horseradish crust

This delicious prime rib is coated with a mushroom and horseradish crust, giving it a spicy and flavorful layer to compliment the juicy meat. Prime rib refers to a roast cut from the small loin end, rib section of beef. It can be standing with the bone in or cut as a rib eye – boneless. If you use a butcher, only have them trim fat that exceeds a 1-inch thickness on the meat. The fat helps flavor the beef. The other flavor factor is how long the meat has aged.
