I just read on another site where a lady froze it, thawed it in the fridge, then put it into the blender and it came out fine and didn't separate again after that. I think it's worth a try. I wanted to do it because there's only my husband and I which means most of the time what's left of even a small container of sour cream gets thrown away since we can't possibly finish it.
I haven't tried it YET but like some of the other posts here say "it comes out lumpy" and also looking kinda like cottage cheese BUT one person said to let it thaw in the fridge and that they put it in a blender to remix it, then back in the fridge overnight and it looked just like "new". I'll try it tonight and let y'all know tomorrow!
