Help I have offered to cook Christmas Dinner this year. I am not a novice cook and have hosted numerous Thanksgving's at my house but not X-Mas. I am a little nervouse about a 5 rib roast and thought I might try a tenderloin. I am cooking for 10. But my familly is used to the beefy, rare, rich roast. Will I dissapoint them with a tenderloin even dressed to the nines?
