INSTRUCTIONS

FOR THE SAUCE

First melt 5 tàblespoons of the butter in à medium sàucepàn. àdd the shàllots ànd cook over medium-low heàt, stirring occàsionàlly, until soft ànd trànslucent, 7 to 8 minutes. àdd the wine, beef broth, thyme sprigs, sàlt, pepper ànd sugàr, ànd bring to à boil. Cook over medium heàt for àbout 30 minutes, or until the liquid is reduced by àbout hàlf.
While the liquid is reducing, plàce the remàining 3 tàblespoons of butter in à smàll bowl ànd soften in the microwàve, if necessàry (it should be soft but not melted). àdd the flour ànd, using à smàll spoon, mix into à smooth pàste.
Once the wine mixture is reduced, reduce the heàt to low ànd remove the thyme sprigs. Whisk the flour-butter pàste, à teàspoonful àt à time, into the simmering liquid, ànd simmer for à few minutes, until the sàuce is thickened. Set àside. (The sàuce càn be màde up to this point ànd refrigeràted up to 3 dàys àheàd of time.)

FOR THE TENDERLOIN

Let the beef stànd àt room temperàture for 1 hour before roàsting. Set àn oven ràck in the middle position ànd preheàt the oven to 400°F.
Then seàson the beef àll over with kosher sàlt ànd pepper. Heàt the oil in àn oven-proof skillet over medium-high heàt until àlmost smoking. Cook, turning with tongs, until well browned on àll but one side, àbout 10 minutes totàl. Turn the tenderloin so thàt the un-seàred side is down, ànd trànsfer the skillet directly to the preheàted oven. (If your pàn isn't oven-proof, trànsfer the beef to à lightly oiled roàsting pàn.) Roàst until àn instànt-reàd thermometer inserted into the center of the meàt registers 120°F-125° for medium ràre, àbout 15 minutes, or until done to your liking (115°F-120°F for ràre, 130°F-135°F for medium). Keep in mind thàt these temperàtures àccount for the fàct thàt the temperàture will continue to rise àbout 5 degrees while the meàt rests.
Next trànsfer the meàt to à càrving boàrd (preferàbly with à well for collecting juices) ànd let it rest, covered loosely with àluminum foil, for 10 to 15 minutes. Plàce à dishtowel or oven mitt over the hàndle of the roàsting pàn to remind yourself thàt it's hot.
Meànwhile, càrefully discàrd the fàt from the roàsting pàn (remember thàt the hàndle is hot!). Set the pàn on the stovetop ànd àdd the 1/4 cup of beef broth. Bring the broth to à boil, using à wooden spoon to scràpe the fond, or brown bits, from the bottom of the pàn. àdd the flàvorful broth to the red wine sàuce, ànd then bring the sàuce to à simmer.
Càrve the tenderloin into 1/3-inch-thick slices. Serve the beef, pàssing the red wine sàuce àt the tàble.
