Steak with Red Wine Sauce

For this delicious preparation, we begin by quickly searing the meat, then cook it in a water bath set to 135 °F / 57 °C, which yields a perfect medium-rare steak. We then finish it in a rich red wine sauce flavored with thyme and fattened up with plenty of butter. The result: a restaurant-level meat treatment that's simple to create and impossible to stop eating—no fancy equipment required.
