My family thoroughly enjoyed this dish, including the picky eaters amongst us! The recipe recommended cooking it for 4 hours on LOW, but there were conflicting reports from other reviewers about the cooking setting. In my experience, following the recipe as is did not result in the dish being fully cooked. I had to increase the heat to HIGH, which caused dinner to be delayed. In the future, I will plan to cook it for 4 hours on HIGH to ensure it is ready on time.

I tried this recipe for the first time last night and it was a success! As someone who had never cooked pork tenderloin before, I found this recipe to be simple and the end result was absolutely delicious. Not being a fan of alcohol, I opted to substitute red wine with Dr Pepper and it worked like a charm - adding depth without overpowering sweetness. The pork turned out flavorful, tender, and I will definitely be making this dish again.

The pork was cooked perfectly in 2.5 hours, reaching a well-done consistency. I recommend checking your pork at the 2-hour mark. If you prefer less garlic, adjust the amount accordingly. After removing the pork, turning the heat up, and adding 2 tablespoons of flour and beef broth or stock created a delicious gravy.
