Instructions

Prepare the Blueberries:
- Mash the blueberries in a large pot using a potato masher or fork. You can mash them fully for a smooth jam or leave some chunks for texture.
Add Sugar and Lemon Juice:
- Stir in the sugar and lemon juice, which helps balance the sweetness and promotes gelling. If using pectin, add it at this point and follow the package instructions.
Cook the Jam:
- Place the pot over medium heat and bring the blueberry mixture to a simmer. Stir frequently to prevent burning. Simmer for 15-20 minutes until the jam thickens. Test the consistency by placing a spoonful on a cold plate. If it runs, cook for a few more minutes. If it holds its shape, it’s ready.
Jar the Jam:
- Sterilize your jars by boiling them for 10 minutes. Ladle the hot jam into the jars, leaving about 1/4 inch of space at the top. Wipe the rims clean with a cloth.
Seal and Cool:
- Place the lids on the jars and screw the bands on finger-tight. For long-term storage, process the jars in a water bath for 10 minutes. Let the jars cool to room temperature. Once cooled, you should hear a “pop” as they seal.
Store and Serve:
- Store the jam in the refrigerator for up to 3 weeks or in a cool, dark pantry for up to 6 months if processed. Serve on toast, pancakes, yogurt, or in pastries.

Notes

You can use honey or maple syrup instead of sugar for a more natural sweetness.For added flavor, try mixing in cinnamon, nutmeg, or ginger while the jam simmers.If you want a smoother jam, use an immersion blender to puree themixture.This jam is also great for gifting or preserving the taste of summer berries all year round.
