Application bundles are directory hierarchies, with the top-level directory having a name that ends with a .app extension. In an application bundle, the first directory in the bundle underneath the top-level directory is usually named Contents.
1 While the roast is resting prepare the au jus; place the roasting pan on top of the stove over high heat. 2  Add in the wine; cook for 8-10 minutes, stirring and scraping any brown bits. 3  Add in the beef stock; cook and reduce the juice by half (this might take about 20 minutes). 4  Add salt and pepper to taste. Set oven to 450Â°F and allow the oven to preheat for a minimum of 15 minutes. 2  Season the roast with only a small amount of salt but lots of fresh ground black pepper pepper (that's all nothing else but a little salt and fresh ground black pepper, using any other spices will take away the flavor from the prime rib!).
4 Place the roast fat side up and rib bones down in a roasting pan. Insert a meat thermometer into the thickest part of the roast, making sure that the thermometer isn't touching a bone. 5 After browning the roast at a 500Â°F temperature in the oven for 15 minutes, reduce the oven temperature to 325Â°F.To figure out the total cooking time, allow about 13-15 minutes per pound for rare and 15-17 minutes per pound for medium rare.oast in oven until thermometer registers 115Â°-120Â°F for rare or 125Â°-130Â°F for medium. (The internal temperature of the roast will continue to rise after you take the roast out of the oven.). Check the temperature of the roast using a meat thermometer 30 to 45 minutes before you expect the roast to be done.
