It is also essential to let the meat rest after cooking, so it is juicy and tender. If you follow these simple guidelines, you will be serving up a perfectly cooked tenderloin that everyone will enjoy!

The better the peaches, the more delicious and nuanced the sauce will be for your peach-mustard dish.
