Key Ingredients for Perfect Blueberry Jam

• 4 cups fresh blueberries (about 1.5 pounds)
• 2 cups granulated sugar
• 2 tablespoons fresh lemon juice
• 1 teaspoon vanilla extract (optional)

Ingredient Notes

Blueberries: Fresh berries yield the best flavor, but frozen work too (no need to thaw). Look for plump, firm berries with deep color.

Sugar: Regular granulated sugar works best. It not only sweetens but helps with preservation and proper gel formation.

Lemon juice: Adds necessary acidity for safe preservation and brightens the blueberry flavor. Always use fresh, not bottled.

Vanilla extract: Optional but adds wonderful depth to complement the berry flavor.

Step-by-Step Blueberry Jam Instructions

1. Rinse blueberries thoroughly and remove any stems or damaged berries.
2. In a large, heavy-bottomed pot, combine blueberries, sugar, and lemon juice. Stir gently to coat the berries.
3. Bring the mixture to a boil over medium-high heat, stirring frequently to prevent sticking or scorching.
4. Once boiling, reduce heat to medium-low and simmer for about 20-25 minutes, stirring occasionally. The mixture will thicken as water evaporates.
5. Test jam readiness by placing a small amount on a chilled plate. If it wrinkles when pushed with your finger after 30 seconds, it’s ready.
6. Remove from heat and stir in vanilla extract if using.
7. Skim off any foam that has formed on the surface.
8. Ladle hot jam into sterilized jars, leaving 1/4-inch headspace.
9. Wipe jar rims clean, seal with lids and bands, and process in a water bath for 10 minutes (optional for longer storage).

Expert Tips for Blueberry Jam Success

• Don’t rush the cooking process – Slow and steady produces the best consistency
• Mash some berries – For chunkier jam, leave most berries whole; for smoother jam, crush about half with potato masher
• The wrinkle test – Place a few small plates in the freezer before starting; use these to test jam consistency
• Safe storage – Refrigerate for up to 3 weeks or properly can for 12+ months shelf stability

Flavor Variations

While this classic blueberry jam recipe is perfect as is, here are some delicious variations to try:

Storing Your Homemade Blueberry Jam

Refrigerator Storage

Store in sealed containers in the refrigerator for up to 3 weeks.

Freezer Storage

For longer storage without canning, freeze in freezer-safe containers for up to 6 months. Leave 1/2 inch headspace for expansion.

Canning for Shelf Stability

For shelf-stable jam, process filled jars in a water bath canner for 10 minutes (adjust for altitude). Properly sealed jars will keep for 12-18 months in a cool, dark place.

Frequently Asked Questions About Blueberry Jam

Why isn’t my jam thickening?

Blueberry jam needs adequate cooking time to reduce and thicken. If your jam seems thin, continue cooking longer. Also, remember it will thicken further as it cools.

Can I reduce the sugar?

Sugar plays an important role in preservation and texture. While you can reduce it slightly, going below 1.5 cups may affect both set and shelf life.

Can I use frozen blueberries?

Yes! Frozen blueberries work perfectly in this recipe. No need to thaw them first; just cook a few minutes longer.

Do I need to add pectin?

No, blueberries naturally contain enough pectin, especially when combined with sugar and acid from lemon juice, to create a proper jam consistency.
