How long can fondant icing be stored in an airtight container?

Fondant icing can be stored in an airtight container for up to 30 days, making it effective for use in various cake decorating projects. Storing fondant properly is crucial for maintaining its texture and pliability. An airtight container prevents air exposure, which can dry out the fondant or lead to hardening, rendering it unusable for decorating.

Additionally, when kept away from light and extreme temperatures, fondant can retain its quality for the maximum duration. It is important to ensure that the container is truly airtight and that the fondant is wrapped properly before placing it in storage.

The other available durations, such as 14 days or 21 days, are shorter than what is typically acceptable for effective fondant preservation, and while it's true that fondant doesn't technically expire in the same way perishable items do, it is advised to treat it with a firm timeline to ensure optimal performance in baking and decoration.
