I have made this incredible recipe before, and it always goes over magnificently.
I'm not worried about the sauce which is a bit time-consuming with reduction times because I can do it ahead of time, but I am more worried about the roast itself. I made it a couple of Easter's ago, and I remember it took longer than I anticipated to get to 125 degrees, and I'll never forget hovering in the kitchen while everything else was done waiting for the temp to rise, and then still needing to allow the 20- to 30-minute resting time. I always allow the roast to come to room temperature before I start cooking it and my oven was regulated. I am going to double the sauce which will be served hot. And I plan on using my meat slicer to cut the roast paper thin. Any advice, or do you think I could cook this meat earlier in the day (say so it is done about an hour earlier than I anticipate) and let it rest at room temperature until ready to slice and serve with the hot sauce. Don't want ice cold beef and hot sauce. I definitely do NOT want it to lose its rareness.
Its the typical, I'd like to be with my guests, not stressing in the kitchen worrying about a lazy cooking roast.
