I tried this recipe last night and it was excellent! I used 3% cream instead of sour cream, because I didn't have it on hand. I added 1 large clove of garlic, diced. I used the tomato paste as directed in the recipe- I wouldn't want to try ketchup..might be sweet. I think this recipe would also be good without tomato paste as well.
I made this for my family last night. I didn't add the paste because I didn't have any on hand. My kids already asked when can we have this again! Thanks for sharing.
This is really good, I just added 3TBS white wine and paprika instead of tomato paste. My husband went crazy over this, will do again and real soon
