I received this recipe on-line from Yahoo! Lifestyle today and just had to post it. We just bought 3 prime rib roasts to freeze because they were on sale for 1/2 price. I am going to try this next time I cook one. The shallot gravy recipe that follows the directions isn't the way I make gravy but I kept it here for those that want to try it. First of all, I would NEVER throw out drippings. I would skim the fat off the top and keep all the drippings I can get. To me, the drippings are gold. Then I add flour (not cornstarch) to the drippings and let it simmer a few minutes to get the floury taste out of it. Then I gradually add liquid from any vegetables I've cooked plus beef bovril (if needed) for more flavour. I would then add the reserved 2 tbsp of herb rub. (that sounds good) You can't have roast beef without a good gravy. Serve with garlic mashed potatoes and roasted vegetables. Man, I think I'll be making this sooner than later.
