I didn't want to buy brandy just to try this dish, but I keep white wine on hand for cooking. I noticed that a couple of reviewers said white wine might be better, so I went ahead with trying. When I got to the stage to add the sour cream, I discovered that I was out, but it was too late so I just used the sauce without, and it was delicious. I don't think the sour cream would have improved it. Hubby loved this dish and I did, too. This will be my regular pork chop recipe now.
