Thaw it in the fridge on a cooling rack to help it dry out.

Slice it into even length thirds.

Sprinkle evenly with a good bit of Kosher salt, along with lots of pepper, and some garlic powder....let sit for at least an hour.

Stack the (3) slices, and tie them together with twine.

Brown all four sides on med-high heat until the meat releases off the bottom of the pan.

Insert meat thermometer, place on a cookie sheet, and roast in a 450° oven until the thermometer reaches 118°

While roasting, brown some mushrooms in the same skillet, and when the mushrooms are cooked, toss in a cup of good red wine, scraping the bottom of the pan. Turn the heat down to medium-low, add a few cloves of crushed garlic, and reduce the liquid by half. Cut off the heat, toss in a half stick of UNSALTED butter, and salt to taste.

Don't worry about sending a thank-you card.

Sounds good, but why cut into thirds and then tie back together?
