Put the roast into a cast iron pan or any baking dish that’s oven-safe. Toss it in the oven and bake at 425°F for 15 minutes.

Turn the oven heat down to 375°F, then roast until your meat thermometer reads 130-135°F for that nice medium-rare finish—this’ll take another 40 minutes or so. For medium, aim for 145°F and remember, once rested, the heat will rise a tad more.

Take the roast out and give it at least 15 minutes under some loosely draped foil. Toss the garlic and string, then cut into thin slices.

On medium heat, melt butter in the dripping-filled pan. Stir in the flour and keep whisking for a minute or two. Pour in a splash of wine, mix continuously as it reduces by half. Add beef stock and cook until thickened up a bit, about 4-5 minutes. Sprinkle in salt and pepper to taste.
