Expiration & Storage Tips
When does meringue expire?
Unopened store-bought meringues can last for up to two weeks at room temperature as long as it is dry and cool. If the meringue has not been opened but has passed the 'Best Before' date on the packaging, it's typically safe to eat for another week. Once opened, meringue should be consumed within three to four days maximum. However, for homemade meringue, it's best to eat it within a day after it was made because of its fragility and tendency to absorb moisture in the air. If you've decided to freeze meringue, it can extend the shelf life by another three months.
How do you tell if meringue is bad?
Spoiled meringues are relatively easy to spot. The most common signs of bad meringue are changes in the color, texture, and smell. If the meringues have developed an off smell or have any signs of mold, then it's time to toss them out. The texture should be crisp on the outside and slightly chewy on the inside; if they are very hard or crumbly, they are likely past their prime. As for the color, it should remain relatively white or light beige. Any darkening or spots indicates that it's likely spoiled.
Tips for storing meringue to extend shelf life
• Store meringues in an airtight container at room temperature. Avoid moist, warm areas, as humidity will make meringues soft and chewy.
• If your kitchen tends to be humid, consider investing in a dehumidifier or store them in a dark cupboard where less moisture tends to gather.
• Homemade meringues are best enjoyed fresh, but if you must store them, do so with a slice of bread in the container. The bread will absorb extra moisture and keep the meringues crisp.
• If you need to store meringues long term, consider freezing them. Ensure they are tightly sealed with both plastic wrap and an airtight container before freezing. To defrost, simply take them out of the freezer and allow them to come to room temperature before serving.
