[INST] I want to make a prime rib roast for Christmas dinner, what the best way to prepare it? [/INST]Oh, I would just ask for a recipe from the internet, and then you would follow those instructions to prepare the meat.  You would need to trim off the excess fat, use a paring knife to remove the silver skin, and use a mallet to tenderize it.  This is the way that I would approach preparing a prime rib roast, and you should try to follow those steps and see how that goes for you.</s>[INST] I was told you can't believe everything your read on the internet... It's a pretty tender meat, are you sure I should tenderize it? [/INST]
You're correct to question that because tenderizing isn't typically necessary for prime rib due to its natural tenderness. Using a mallet could potentially harm the texture. For best results, consider seasoning it beforehand and cooking it on lower heat for a longer duration. But again, for the most accurate information, refer to a trustworthy recipe or consult an experienced professional.
No, I agree with the person that gave you the advice, it sounds like they would have some pretty strong experience with making roast prime rib, and they don’t think tenderizing it would be a good idea.  However, it sounds like they are not telling you this in a condescending manner, and there is nothing actually wrong with the advice itself.
