FAQs
What type of blueberries should I use for jam?
You can use either fresh or frozen blueberries. Wild blueberries have a more intense flavor, while cultivated ones are larger and sweeter.
Can I make this jam without sugar?
You can reduce the sugar or use a sugar substitute, but keep in mind it will affect the preservation and texture. Pectin may be needed for proper thickening.
How do I thicken blueberry jam naturally?
Allow the jam to simmer longer to evaporate excess liquid, or use ingredients like chia seeds or a bit of natural pectin from apples or citrus.
Is lemon juice necessary in blueberry jam?
Yes, lemon juice helps balance the sweetness and provides acidity, which is essential for safe preservation.
Can I double the recipe?
Yes, but be sure to use a large enough pot and stir frequently to prevent sticking and uneven cooking.
Why is my jam too runny?
It may need to cook longer. Use the chilled plate test to check if it’s ready. If not, return it to the heat and simmer until thickened.
How long does homemade blueberry jam last?
If properly canned, it can last up to a year unopened. In the fridge, it lasts up to 3 weeks after opening.
Can I freeze homemade jam?

Do I need pectin for this recipe?
No, blueberries naturally contain some pectin, and lemon juice helps. The jam thickens through simmering and reduction.
Can I use this jam in baking?
Absolutely. It’s great for thumbprint cookies, jam bars, cake fillings, or even swirled into muffins or cheesecake.
