What is the ideal internal temperature for a cooked pork loin?
The ideal internal temperature for a cooked pork loin is 145°F (63°C). It’s essential to use a meat thermometer to ensure the pork loin reaches this temperature, especially when cooking to a specific time per pound. This temperature ensures the pork is cooked through and safe to eat.
It’s also important to note that the internal temperature of the pork loin will continue to rise slightly after it’s removed from the heat. This is known as carryover cooking, and it’s essential to consider this when checking the internal temperature. To avoid overcooking, remove the pork loin from the heat when it reaches an internal temperature of 140°F (60°C) to 142°F (61°C).
How do I determine the cooking time for a pork loin based on its weight?
