How to Know if Sour Cream has Expired

As with most things, sour cream will develop an unfamiliar look, taste, and smell after spoiling.


If you notice that your sour cream has become yellow or discolored in any way, discontinue use.


If you notice mold on sour cream, it is yet another sign of spoilage.


Sour cream that doesn’t taste or smell quite right is also likely unsafe to eat.


And most importantly, if your sour cream has gone 1-3 weeks past expiry, it is best you toss it and purchase fresh sour cream.


If you find that your sour cream has gone bad, you can replace the sour cream with buttermilk in the case of dressings or baked goodies.
