Expiration & Storage Tips
When does graham cracker expire?
Unopened packages of graham crackers usually have an expiration date printed on the packaging, which typically gives you at least several months of shelf life from the date of purchase. However, once the package has been opened, they can start to lose their crispness after about 1-2 weeks if not properly stored. Homemade graham crackers can be stored at room temperature and stay good for about 2-3 weeks. If you decide to freeze graham crackers, they can last up to 3 months with retained quality.
How do you tell if graham cracker is bad?
It's fairly easy to determine if graham crackers have gone bad. Their primary characteristic when fresh is a crispy, crunchy texture. When they start to go bad, they become soft and lose their crunch. Beyond this, if they develop an off smell or start to show signs of mold, then they should be discarded immediately.
Tips for storing graham cracker to extend shelf life
• Keep the crackers in an air-tight container for maximum freshness. This can significantly extend their shelf life once the package has been opened.
• If you've made your own graham crackers, allow them to cool completely before storing them in an air-tight container at room temperature.
• If you have lots of graham crackers and want to preserve them, freezing is a good option. Transfer the crackers to a freezer bag, squeeze out the air, and store them in the freezer. When you want to eat them, allow the packets to reach room temperature before opening, this will prevent them from going soggy due to condensation.
