I have a container of sour cram that got slightly frozen, not solid just part of the top. You can tell that the consistency is not what it should be. I need to make WASC cupcakes for my DD birthday. I have a new container of sour cream, but I hate to waste the one.
Sour cream breaks down and separates when frozen and thawed. You can stir it back together, but it won't have the texture you expect. it is one of the dairy products that does NOT freeze well. The cultures break down and separate, and there's nothing you can do about it. Although it won't be great on a baked potato, you can still cook with it.
Thanks for the help. I have two refrigerators, one of them I have to keep and eye on as it will freeze things, usually never solid but enough that you can see ice crystals. I just don't want a batch of cupcakes that didin't turn out right and I have to rebake.
