Place your pork tenderloin on top of the carrots and onions and season with salt and pepper.
In a medium mixing bowl, whisk together stock, apricot preserves, mustard and thyme leaves.
Pour glaze mixture over tenderloin.
Cover and cook on low for 6 hours, or until tender and cooked through.
Notes
This recipe works best with a pork tenderloin.If you would like the apricot sauce to be thicker than it already is, you can make that happen with a few tablespoons water and tablespoons cornstarch. Simply mix together 2 tablespoons of cold water with 1 tablespoon of cornstarch in a small bowl, and stir cornstarch mixture. Then pour the cornstarch mixture into the warm apricot sauce and mix it all together until the sauce begins to thicken up.Recipe adapted from Paula Deen.
