I have a question about step 5 on the recipe "Ann Seranne's Rib Roast of Beef" from Genius Recipes. It says:
"Allow the roast to remain in the oven until oven is lukewarm, or about two hours."
I only have one oven and need to use the oven to cook sides. How long can the roast rest outside the oven after the initial 2 hours resting in the oven and still be warm enough to serve
