Expiration & Storage Tips
When does meringue powder expire?
Meringue powder, when unopened, can typically last up to two years from the manufacturing date. Once opened, the quality remains best for about 6 months. Homemade versions are not common as this ingredient needs specific manufacturing methods. When it comes to freezing, meringue powder doesn't usually need it due to its long shelf life but be sure freezing won't have any harm.
How do you tell if meringue powder is bad?
To realise if your meringue powder has gone bad, you will need to be attentive to a few signs. Check the color and texture. It should be white and powdery. If it has become hard or yellowish, it may not be fresh anymore. Also, sniff the powder. If it has an off or sour smell, it's time to discard it. In any case, if you're unsure, it's best to err on the side of caution and throw it out.
Tips for storing meringue powder to extend shelf life
• Make sure you store your meringue powder in a cool and dry area. Avoid exposing it to heat or moisture.
• After using, always seal the package tightly to protect it from humidity and prolong its shelf life.
• If you live in a humid area, consider storing your meringue powder with a small packet of food-safe desiccant to prevent it from clumping.
• Don't use a wet spoon or any damp object to scoop the powder to avoid introducing any moisture.
• You may also store meringue powder in an air-tight container to extend its shelf life even further.
