Can I make jam from frozen blueberries?
Can you use frozen blueberries to make jam? Yes, of course, you can use frozen blueberries. If you are using frozen berries, let the blueberries macerate in sugar and lemon juice for a few hours before cooking. This softens the blueberry skin considerably.
How do I make my freezer jam set?
Often the instructions for freezer jam include ladling the jam into clean, lidded jars and then allowing the jam to sit out for 24 hours before storing. This “sitting” time allows the pectin to fully set.
Can you use glass jars for freezer jam?
Can you use glass jars for freezer jam? Yes! I love to use glass mason jars for freezer jam! You can also use just about any container that is freezer friendly.
How do you fix blueberry jam that didn’t set?
Canning 101: How To Save Runny Jam

How long does homemade blueberry jam last?
Properly sealed and processed jars of blueberry jam should be stored in a cool, dark, dry place (such as a pantry). The homemade blueberry jam will last for up to 1 year.
How do you thicken blueberry jam?
Blueberries are high in natural pectin, which means you don’t need to add any. What you do need to add is lemon juice. When you heat the blueberries and sugar together, natural pectin is released. The lemon juice then bonds with the pectin, creating a gel and thickening your jam.
Why isn’t my jam thickening?
Generally speaking, if your jam doesn’t firm up, you were short in pectin, sugar or acidity or didn’t get a hard boil. No matter how much you stir, you won’t get effective heat penetration in larger batches, so some pectin gets overcooked, while other pectin is not activated.
How long is freezer jam good for in the freezer?
Fill jars with jam, making sure to leave 3/4-inch at the top so that it can expand. Store in the freezer for as long as 6 months. Once jam is defrosted, it will keep up to a week in the refrigerator.
How can I thicken jam without pectin?
The secret ingredient to making jam without pectin is time. The fruit and sugar need plenty of time to cook and thicken. A long, slow boil drives the moisture out of the fruit, helping to preserve and thicken it at the same time. Fruit varies in water content as well, and some fruits may take longer to jam up.
Is Sure Jell the same as pectin?
Every brand of pectin is a bit different, so, use what is recommended. I use Certo and Sure – Jell because they are sister-products marketed by Kraft foods and give me great results. While liquid and powdered pectin both achieve the same thing, they’re a thickener, they are not used in the same manner.
How long can homemade jam last?
For homemade jams made using sugar and processed by canning in a hot water bath, you can expect to get about two years of shelf life when stored in a cool, dry place. Once opened, keep your homemade jam in the refrigerator for up to three months.
Can I freeze Mason jars with metal lids?
Can I freeze mason jars with metal lids? Yes. How can I avoid broken glass when freezing in jars? Make sure you’re using a wide mouth jar like these Wide-Mouth 16-oz Mason Jars.
Does lemon juice thicken jam?
The lemon juice lowers the pH of the jam mixture, which also neutralizes those negative charges on the strands of pectin, so they can now assemble into a network that will “set” your jam.
Can you Reboil jam that hasn’t set?
If it has you know your jelly or jam is ready. If it still hasn’t set then add another 1/4 to 1/2 a package of no-sugar pectin and bring it to a boil for 1 minute again. Remove the jars from the heat and skim the foam off.
How can I thicken jam without cornstarch?
Add pectin. Whisk a tablespoon of powdered pectin (preferably the no-sugar-needed variety) into the pot of cooking jam. Test for thickness and add another tablespoon if needed.
