How Long Will Fondant Last

How Long Will Fondant Lastの要点や背景をコンパクトにまとめました。全体像を一目で把握できます。

Commercially bought fondant (like the Wilton stuff) is surprisingly forgiving. If you store it properly, it can last anywhere from several months to over a year past its printed expiration date. Yes, you read that right—it’s practically the Twinkie of the cake world.

But here’s the catch: you have to treat it like a diva backstage at a concert. Air is its enemy, and humidity is its frenemy. Leave it out on the counter, and it will dry into a cracked, crusty mess faster than you can say "buttercream."

The "Sweater Weather" Rule

Think of fondant like a cozy wool sweater. It likes to be wrapped up tight. The best way to store it is to smother it in a thin layer of vegetable shortening (Crisco is perfect), then wrap it like a mummy in plastic wrap. No gaps! Then, pop it into an airtight zip-top bag.

Keep it in a cool, dark cabinet—not the fridge! Never put fondant in the refrigerator. The fridge will make it sweat and become sticky and gross, like a forgotten container of leftovers. Room temperature is its happy place.
