Expiration & Storage Tips
When does white frosting expire?
Store-bought white frosting is generally safe for use up to one month past the printed date on the packaging when unopened and stored at room temperature. After opening, it's best to enjoy your frosting within two weeks for the freshest flavor and texture, ensuring it's sealed tightly after each use. If you've made your frosting at home, aim to consume this within one week, as homemade frosting doesn't contain any preservatives. Though it's not common to freeze frosting due to texture changes upon defrosting, if necessary, it can be frozen for up to 3 months.
How do you tell if white frosting is bad?
Spotting spoiled frosting isn't too difficult! First, you'll notice a change in texture, the frosting may become hard or crusty. Secondly, look for mold- small growing spots (usually green, blue, or black) that indicate bacterial growth. And of course, a smell check can also be a good indicator. Fresher frosting has a sweet, pleasant scent, so if you notice any off-putting or sour aroma, it's a good indication that your frosting has spoiled.
Tips for storing white frosting to extend shelf life
• Always tightly seal the cover after using to prevent air from entering the container and moisture loss.
• For homemade frosting, refrigerate it in an airtight container immediately after use.
• After opening, place the store-bought frosting in the refrigerator for extended freshness.
• Avoid using wet utensils to scoop frosting; extra moisture can expedite the spoilage process.
• For long-term storage, consider freezing mixtures in small, labeled, airtight containers. Defrost it overnight in the refrigerator before usage.
