Some of the ingredients in this sauce may come as a surprise. I was rifling through the refrigerator contemplating what would go well with pork, when my eyes fell on the sweet relish. Seemed a bit weird, but I liked the idea. After all, relish is great on hotdogs and goes perfectly with mustard, so why not on a pork tenderloin?

The result was nothing even close to any food you might find at a ball park. Mustard, garlic and thyme make this cream sauce delicious, but the hint of sweet relish really makes it sing.

This recipe works well for the busy cook.  Pork tenderloin cooks quickly and this dish requires only one pan from start to finish. The entire recipe only takes about 35 minutes or so to put together.
