Recipe Tips
When buying a pork loin, choose one with pinkish-red color with some marbling in the meat. Do not pick up a loin with meat that is pale in color or has dark spots in the fat.
How much pork loin do I need per person? The rule of thumb is to plan on 1/2 pound per person when serving pork, a roast, steak or chicken.
It's always best to cook the loin right away but it can stay in the refrigerator for up to 3 days before cooking. Make sure you let it sit at room temperature for at least 30 minutes before cooking.
Pork is ready when it measures 145°F with your meat thermometer.
