How To Tell If Jam Is Bad?
Fortunately, there are a few other ways to determine whether your jam is terrible. Typically, jam is best consumed within six months of its best-by date. However, if it has gone past its best-by date, it’s probably already gone bad. Moreover, it’s also possible to smell the jam and find if it’s still edible. This way, you can save a lot of money when buying your favorite jam.
Store it in a dark, cool place if the jar is unopened. This way, it won’t be exposed to the heat of your kitchen.
