Does jello get too old to use?

Yes, jello does get too old to use. The expiration date on the package is a good indicator of when the jello should be used by, but it can sometimes last a bit longer. If the jello has been stored properly, in a cool, dry place, it can usually last for up to 2 months past the expiration date. However, it's important to check the jello for any signs of spoilage before using it, such as mold, discoloration, or an off odor. If the jello shows any signs of spoilage, it should be discarded immediately.
