Expiration & Storage Tips
When does tostada shell expire?
An unopened package of store-bought tostada shells has a shelf life of about 2-3 weeks past the printed date on the package, assuming they've been stored properly. Once the package has been opened, its best to consume them within 7-10 days for optimum freshness and to avoid staleness. If tostada shells are homemade, they should be eaten within 2-3 days for the best quality. If you've taken the extra step to freeze your tostada shells, they can last up to 2-3 months.
How do you tell if tostada shell is bad?
Telling if a tostada shell has gone bad is quite simple. First, look for any visible signs of mold or discoloration on the shell. These are clear signs of spoilage and the shell should not be consumed. The second sign to watch out for is a change in texture. A good tostada shell should be crisp and break easily. If it feels soft, rubbery or has a stale taste, it's past its prime and it's time to toss it.
Tips for storing tostada shell to extend shelf life
• Always store tostada shells in a cool, dry place, away from direct sunlight. The pantry or a kitchen cabinet can serve just fine.
• Once opened, store leftover shells in an airtight container or sealable food storage bag to protect them from moisture and air, which cause them to stale faster.
• If you need to store them for an extended period, consider freezing the shells. To freeze, wrap tightly in plastic wrap, then place them in a freezer bag. And when it's time to defrost, lay them out on a counter at room temperature for an hour or two before use.
