If you want to see how this pork should really look, make sure to check out Donna's (My Tasty Treasure's) blog...her pictures were WAY better!!! We had some minor issues as far as the cooking time goes and had to cut into it several different times. I had to laugh, because I bought a pork tenderloin, having absolutely no idea what I was going to do with it and then I came across this recipe on Allrecipes.com. To my surprise, Donna posted the very same recipe the next day! She is an absolutely amazing cook, so the fact that she recommended it, let me know that it was definitely worth trying. It was wonderful, although I think I ended up using a 3 1/2 pound pork loin instead of (2) 3/4 lb pork tenderloins, so I should have researched the cooking time a little more thoroughly as I grossly underestimated the amount of time it would need. Tomorrow, I'll be posting a recipe that we tried to utilize the leftovers!!!
Place soy sauce, brown sugar, sherry, dried onion, cinnamon, olive oil, and a touch of garlic powder in a large resealable plastic bag. Seal, and shake to mix. Place pork in bag with marinade, seal, and refrigerate for 6 to 12 hours.
Preheat grill for high heat. Lightly oil grate. Place tenderloins on grill, and discard marinade. Cook 20 minutes, or to desired doneness. Slice into medallions, and serve.
