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."
Jam and jelly will deteriorate quicker when stored outside the fridge. This is especially true if the ambient (air) temperature is high, which can cause rancidity or separation of ingredients. It's worth noting that different products will degrade at different rates at room temperature.

Most of our jellies, jams and fruit spreads do not contain preservatives. As long as the containers are refrigerated after opening, they should maintain their freshness for several months.
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.
Your jelly should set in the fridge in around 4 hours. Note: you can add fruit or juice, but avoid fresh pineapple, kiwi or papaya as these fruits will stop your jelly from setting.
Do I have to refrigerate Smucker's peanut butter? The food items we produce are classified as non-perishable. Refrigeration is not necessary, although it does slow down the oil-separation process.
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.
So, jam and jelly will deteriorate quicker when stored outside the fridge. This is especially true if the ambient (air) temperature is high, which can cause rancidity or separation of ingredients.
If you've made jam and waited for it to cool, but it is still runny, pour the jam back into a saucepan and bring it back to a boil.Boil until the jam starts to reduce and therefore thickens.
If it runs slow, it's set! You can also let the spoonful of jam sit on the cold plate for 30 seconds and then push it with your spoon or finger. If it wrinkles up, you've reached your setting point. TIP: Use a white plate so you can see the jam clearly.
sometimes if it doesn't set within 12–24 hours but has at least a partial set, if you give it a week or two, it will firm up some. if it is syrupy but not solidifying at all after a few days, it is probably not going to set. then you have two options, either use as a syrup or you can reprocess it.
If you pour it into individual bowls, it will set in a couple of hours. If it is all in one mould/bowl, you need at least overnight and make sure it is in the fridge.
THE PRESERVATION OF JAM DEPENDS ON ITS SUGAR CONTENT
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.

How long can you leave a peanut butter and jelly sandwich out? Most types of sandwiches can be safely left out at room temperature for about two hours — or one hour if the temperature is above 90 degrees Fahrenheit.
