Time to make the glaze! I totally wanted to style up my tenderloin for this particular meal so I went to the fridge to see what I had on hand to make a tasty glaze. This is what I came up with. In a bowl, add your mustard, horseradish, Garlic & Herb Seasoning and salt and pepper to taste. Whisk all together and BAM you have a nice, flavor balanced glaze. REMINDER—Start with a little less of each ingredient and taste. Add more as desired. You can always add but can not take away. Pour your glaze over your pork tenderloin on a foil lined baking dish and evenly coat all sides and every crevice. Bake according to package directions which on mine is 15-20 minutes per pound. Oven temps vary drastically so I like to go to the latter of the cooking times. When your tenderloin is done to your internal temperature satisfaction, remove it from the oven and tent it with some aluminum foil and let it rest, while you prep the tates. It will continue to cook a little as well so give it a little peak every now and then so not to overcook.
