Can You Freeze Sour Cream?

7. How do I thaw sour cream?

Whether you’ve stored sour cream in its original unopened container or not, the thawing process is exactly the same. Simply transfer the container from the freezer to the fridge and let it thaw naturally. Never thaw sour cream outside of the refrigerator, as this might invite bacterial growth. Once the ice crystals are gone, you can attempt to regain some of the original texture of the sour cream by whipping it or putting it in the blender and putting it back in the fridge to let it set.

Pro tip: try adding one or two tablespoons of cornstarch before you stir for added thickening power.
