What is breakfast toast without your favorite jam or jelly? Or that PBJ? It is no secret that jams and jellies are versatile, delectable spreads that can add just the right touch to anything from a stack of our Test Kitchen's Favorite Buttermilk Pancakes to a charcuterie board. Whether you make your own from scratch or buy one of these toppings, you'll need to store them properly to make sure they don't spoil. We asked a food safety expert to share the best storage method to preserve their freshness.
If you just bought a jar of jam or jelly, you could keep it stored in your kitchen cabinet—as it is shelf stable until it is opened, explains Nicole Richard, a research associate and food safety specialist at theUniversity of Rhode Island's Food Safety Outreach and Research Program. Sealed jars of homemade preserves can also be stored at room temperature. Once the jam or jelly is opened, however, it is best to refrigerate them. Richard explains that this prevents mold and yeastfrom growing.If not refrigerated, opened jams and jellies are likely to spoil quicker. "Storage of opened jams and jellies in the refrigerator slows the growth of spoilage microorganisms, therefore, extending the shelf life of the food," she says.
When to Throw Out Jams and Jellies
Since jams and jellies are acidic, Richard explains that the organisms of concern are molds and yeasts. You'll know it's time to toss your jams or jellies if you see mold, yeast growth, or other signs of spoilage. She notes that fermented-, alcohol-, or yeast-like odors coming from these spreads are also signs that they are expired. "Additionally, mold can send shoots down into the jam or jelly that are not visible, therefore, scooping out the mold is not a safe option," Richard shares. "The jam should be thrown away or composted."

If it's too loose, you can always cook it more or simply refrigerate it, which will firm it too. If it's too firm-set, you can loosen it with a spoonful of hot water until it's the consistency you like.
Jellies and jams do not need to go in the fridge because they have a water activity of around 0.80, and their pH is usually around 3. So they don't have enough moisture to support bacteria and are too acidic for them as well. Conclusion: Keep your jams and jellies wherever you want to.
Foodsafety.gov agrees that most commercial peanut butters that contain stabilizers will last two to three months at room temperature after opening (for natural peanut butters, they recommend refrigerating to preserve the quality).
Unless you're a busy diner going through and refilling ketchup bottles every day or two, you should store your ketchup in the fridge. This is because, just like pickles, the flavor and texture declines after you open the bottle or jar and the ketchup is exposed to air.
To ensure that your peanut butter lasts longer, it's important to store it properly. Although it doesn't need to be refrigerated, cold temperatures ensure it lasts longer. If you prefer not to refrigerate your peanut butter, aim to keep it in a cool, dark place, such as the pantry.
Once it sets we always suggest keeping it in the fridge to keep it nice and cold as well as fresh. If it is an environment that is hot it might re-melt again to become liquid. It should not spoil if left out for a long period of time as long as it is in a cool environment.
Refrigeration is not necessary and may make the product difficult to spread. Natural peanut butters that do not contain any stabilizers, like our Smucker's 'Adams' and 'Laura Scudder's' natural peanut butter products, are typically best stored at room temperature whether opened or unopened.”
According to the National Peanut Board, unopened, commercially processed peanut butter lasts for up to 9 months in the pantry, while opened conventional peanut butter lasts up to 3 months in the pantry and up to 9 months in the refrigerator.
Sealed jars of homemade preserves can also be stored at room temperature. Once the jam or jelly is opened, however, it is best to refrigerate them. Richard explains that this prevents mold and yeast from growing.
Jams and jellies are both soft, sweet spreads made from fruit, sugar and pectin. The main difference between jam and jelly is that jam is made with fruit whereas jelly is made with fruit juice.
Home-made jam should be stored in a cool, dry place away from direct light and used within 12 months of making. Once opened the jar should be stored in the refrigerator and used within one month. We would suggest discarding any jars of jam that have mould growing on top.
Nowadays, sugar substitute and jelly are used before your condiment will set. So, refrigeration is advised but check content for preservatives. With these, a short time without refrigeration is OK. But put them back into the fridge as soon as you can.
While, in general, an unopened industrial jam can be preserved for about 2 years at room temperature and away from light, not all jams are made up of the same ingredients.
Once it sets we always suggest keeping it in the fridge to keep it nice and cold as well as fresh. If it is an environment that is hot it might re-melt again to become liquid. It should not spoil if left out for a long period of time as long as it is in a cool environment.
Shelf-stable condiments, like stone ground mustard, red wine vinegar, strawberry preserves, and wing sauce, don't need to be as cold as other perishable foods like milk, eggs, and meat, so they can hang out on your refrigerator door.
