I have a question about the recipe "Ann Seranne's Rib Roast of Beef" from Genius Recipes. Can I use this recipe for a one rib prime roast... the recipe says 2 to 4.
I'll repost my answer here, just in case you didn't see it on the recipe thread: You could try it, reducing the cook time proportionally (see the chart above), but I'd strongly recommend a probe thermometer to keep track of the temperature (they're cheap!).
You definitely need a probe thermometer. I made a one rib roast for Christmas Eve. Also important to take it out and let it rest before it gets to internal temp that you want.
Yes, it works just fine.
