People have done weird things with vintage canes. Some sell them on eBay as "vintage Christmas decor." Yes, people pay money for old candy canes.
You can also melt them down. Old canes make excellent for baking. Crush them up for cookies, melt them into hot chocolate, or use them as a weird potpourri.
One blogger ate a candy cane from 1998. She said it tasted like "powdered sugar and regret." No thanks.
The Legend of the 100-Year-Old Cane
There’s a rumor that some extremely old candy canes exist in museum collections. Are they edible? Absolutely not. Would a scientist eat one? Probably, if they were brave.
In theory, if sealed in an airtight jar, a candy cane could last centuries. It’s a sugar fossil. Future archaeologists might find a box of striped peppermint sticks and think we worshipped them.
Which, honestly, we kind of did. We hung them on trees. We gave them as gifts. We let them sit in drawers for decades. That’s a religion.
