I have the same recipe and I love it. The only thing I did, differently, was to add some tomato paste which gave the sauce a richer taste, and a blend of hot and sweet paprika. I also served this over creamy mashed potatoes. The next time, I plan to sear the pork in some olive oil, remove it, then cook the onions & garlic. I think the sauce would have an even more flavorful and rich taste to it. Very low budget meal, too!
Heavy cream? Butter?? 2teaspoon of paprika only.
