I assume it rests in the oven with the heat turned off before final rest for 15 minutes on the counter?

Thank you for your question. I have edited the instructions to clarify. When the roast is done (at least 125 degrees all over - test in several places with your thermometer), take it out of the oven. Cover it with foil and let it sit/rest on the counter like that for at least 15 minutes. It will continue cooking while it rests and be perfect when you carve.

Hi, David. Remove the roast from the oven to rest. Cover it with foil so that it stays warm. The roast will continue to cook on its own just sitting there like that and be perfect when you are ready to carve it - 15 or so minutes later. I hope you enjoy it!
