If you’ve stood in the grocery store wondering whether pork loin and pork tenderloin are basically the same thing, you’re not alone. Here’s what I have learned cooking with both.

These are completely different cuts. Pork loin is large and slow-roasted. Pork tenderloin is small and quick-cooked. Many recipes confuse them – read carefully and look at the weight to know which you have.
