Expiration & Storage Tips
When does strawberry jam expire?
An unopened jar of strawberry jam can last up to two years in a cool, dark pantry when stored properly, even past the 'best by' date printed on the label. However, always check the manufacturer's instructions on the package since some brands may have different recommendations. Once opened, the jam usually lasts 6 to 9 months in the refrigerator. If you decide to freeze an opened jar of jam, it can last up to a year. Homemade strawberry jam, if canned properly, can last up to two years unopened in the pantry and about a month in the fridge once opened.
How do you tell if strawberry jam is bad?
Checking whether your strawberry jam has gone bad might seem a bit tricky, but it's actually pretty straightforward. A key indicator is mold, which usually appears as a fuzzy growth on the surface. It can be blue, green, white, or even black. Other signs include an off smell - a scent that’s different from the normal sweet strawberry aroma. In addition, any fizzy or fermentation smell or flavor is also a sign that your jam has gone bad. If the jam seems watery or runny, it may also indicate spoilage.
Tips for storing strawberry jam to extend shelf life
• Keep the jam in a cool, dark place until you open it. This could be your pantry or a kitchen cupboard. Avoid placing unopened jam near a stove or in direct sunlight.
• Once you have opened the jam, always store it in the refrigerator. Make sure that it is well sealed with a lid.
• Always use a clean spoon when scooping out the jam to prevent introducing bacteria into the jar.
• Consider dividing the jam into smaller portions before freezing. This way, you can defrost only the quantity you need at a time, preventing constant freezing and thawing which may degrade the quality of the jam.
• If freezing, ensure the jam jar is freezer-safe to prevent cracking or breaking. Leave some headspace for the jam to expand as it freezes. To defrost, simply place it in the refrigerator for a day or two before using.
