Cotton candy, also called spun sugar or fairy floss, is readily available at fairs and carnivals. Bring home an extra package of cotton candy and preserve it for eating later. The structure of cotton candy and its shelf life depends on the storage temperature and humidity level. Any moisture from the air will cause the cotton candy to clump into a tight ball, but even in a humid climate, you can indefinitely keep your cotton candy fresh.

Things You'll Need

Transfer the cotton candy to a resealable freezer bag.

Gently press out excess air from around the sides of the cotton candy without squashing the cotton candy. Seal the bag.

Put the sealed bag into an air-tight container and seal. This double barrier keeps out air and moisture to ensure the freshness of the cotton candy.

Freeze the cotton candy indefinitely, or store in a cool, dark place for up to two months.

Eat the frozen cotton candy immediately after removing it from the freezer and discard any leftovers. The exposure to the warm temperatures and humidity upon removal from the freezer will cause the cotton candy to shrink and clump.
