Pork tenderloin is one of the leanest cuts of pork, making it both healthy and quick-cooking. Sous vide is perfect for this cut because it prevents the common problem of dry, overcooked pork. Modern food safety guidelines allow pork to be cooked to lower temperatures than the outdated 160°F recommendation, resulting in juicy, tender meat with a slight blush of pink. This mild-flavored cut is a blank canvas for marinades, rubs, and sauces, making it incredibly versatile for weeknight dinners and special occasions alike.
