Why This Recipe Works

Patting the meat dry for our Pork Tenderloin with Roasted Potatoes and Shallots recipe removed excess moisture from the exterior, allowing it to sear better in the skillet. Cooking the pork in the same skillet we used to cook the potatoes saved on cleanup and also imparted layers of flavor to the tenderloin. Precooking the potatoes and shallots in the microwave reduced their stovetop cooking time to just a few minutes.
