Expiration & Storage Tips
When does marmalade expire?
For an unopened jar of commercial marmalade, it stays good for a year to eighteen months if stored in a cool, dark place like pantry. Once opened, keep it refrigerated and it should last for up to a year, depending on the usage. Be sure to always use a clean spoon to scoop out the marmalade to avoid introducing bacteria. If you've made a homemade batch, consume it within two weeks when stored in the refrigerator, or you can freeze it for up to a year.
How do you tell if marmalade is bad?
Signs that marmalade has spoiled include a change in color or texture, an off smell, or if it’s begun to grow mold. Mold is a clear indicator that it's beyond saving and you'll want to discard the jar immediately. In terms of texture changes, if it seems overly watery or excessively clumpy and dry, it is probably past its consumption date.
