Expiration & Storage Tips
When does puff pastry shell expire?
Unopened puff pastry shells bought from a store usually have a printed 'best-by' date on packaging, typically around 1-2 months from the purchase, but can often last a little longer if unopened. Once you break the seal, it's best to consume it within a week for optimal freshness. Since they are highly perishable, homemade puff pastry should ideally be used the same day but can last up to 2 days in the refrigerator if stored properly. You can also freeze puff pastry shells for up to two months.
How do you tell if puff pastry shell is bad?
First of all, check for visible signs of mold or unusual discoloration. If it looks fine, give it a sniff. If it has a sour, off smell, it's time to discard it. Another indicator of spoiled puff pastry is a change in texture. If the pastry feels soggy, overly wet, or sticks to the package, it's likely past its prime, and you should throw it away.
Tips for storing puff pastry shell to extend shelf life
• Always store puff pastry shells in a cool, dark place (like a pantry or refrigerator) when not in use.
• For a longer shelf life, consider freezing it. Wrap it tightly in plastic film and put it in a sealable freezer bag. To defrost, leave it in the refrigerator overnight.
• Try to use open packages within a week. The longer it's left after opening, the greater chance it has to absorb odd flavors from its surroundings or go dry.
• Handle puff pastry with dry hands. Any moisture can start the pastry going bad.
• If you've made a dessert or other dish with puff pastry, it's best to keep it in an airtight container in the fridge.
