Store Sour Cream Safely With One Clever Sealing Trick
BY SIMONE GERBER
To prevent the untimely spoilage of sour cream, place a square of plastic wrap over the container's opening and press down until it makes full contact with the top of the cream.
A main factor that accelerates the expiration of sour cream is air exposure. Storing it in an airtight container reduces this exposure, but it still contains some trapped air.
Plastic wrap eliminates this problem by creating a barrier. This technique can stretch the lifespan of your sour cream to over a month.
