Is it safe to bake with sour cream after expiration date?

No, it's not safe to bake with sour cream after the expiration date. Consuming expired dairy products can lead to foodborne illness, including symptoms like stomach cramps, nausea, vomiting, and diarrhea. Even if you use the sour cream in baking, the heat may not be enough to eliminate the risk of bacteria.

It's important to follow the expiration dates on food products to ensure that you are consuming them while they are still safe. If you are unsure whether a dairy product is still good, it's best to discard it.
