Don’t confuse pork tenderloin with pork loin. The tenderloin is a smaller cut, averaging about 1 pound. Look for meat with relatively firm, pink flesh. Pale or brownish meat is a sign it’s past prime.
Prep
Its relatively small size means you can cook up tenderloin in less than 30 minutes, making it a perfect weeknight option. It also takes well to marinades and rubs. If sold with a silvery skin, trim this off before cooking and then prepare with a one-two punch: Brown all sides in an oven-proof skillet, and then transfer to a 400°F oven. The cut is also great grilled, which imparts smoky flavor. The leanness means it’s easy to overcook, so pay attention when over the fire or in the oven, and cook only to an internal temperature of 145°F, letting rest 5 minutes before slicing. Going the extra step to brine pork tenderloin in a salty liquid (like leftover olive brine) for a few hours before cooking will help ensure you slice into moist meat.
Make It Last
Once home from the butcher, keep tenderloin in the back of the fridge on a plate for up to three days. Beyond that, store tightly wrapped in the freezer for up to three months.
