BUY GOOD MEAT
The quality of the meat makes ALL the difference, so get the good stuff, if you can! (I link to my favorite source in the post).
YOU NEED A THERMOMETER
Good rib roast requires cooking to very specific temperatures. Know your temps with a high quality wireless thermometer!
Proper prime rib can't be rushed.
HAVE FLEXIBLE TIMING
SALT
This is likely a giant hunk of meat. It'll take a lot of salt to season it properly!
MIREPOIX
This magic combo of onions, celery, and carrots will leave your jus tasting incredible!
YOUR BEST KNIFE
And if you don't have a good one, get one. This meat needs precise slicing!
