Ingredients:
- 4 cups fresh blueberries (or frozen, thawed)
- 2 cups granulated sugar
- 2 tablespoons lemon juice
- 1/4 teaspoon ground cinnamon (optional)
- 1/2 teaspoon vanilla extract (optional)
- 1 packet (1.75 oz) fruit pectin (optional, for extra thickness)
Instructions:
1. Prepare the Blueberries
- Wash the blueberries thoroughly, removing any stems or leaves. If using frozen blueberries, thaw them completely and drain excess water.
2. Cook the Blueberries
- In a large, heavy-bottomed pot, combine the blueberries, sugar, and lemon juice. Stir occasionally as the mixture heats up and the blueberries start to release their juice.
- If you prefer a smoother jam, you can mash the blueberries with a potato masher or blend them slightly using an immersion blender.
3. Simmer and Thicken
- Bring the mixture to a gentle boil over medium heat, then reduce the heat and let it simmer for 15-20 minutes, stirring often.
- If using fruit pectin, stir it in according to the package instructions. This will help the jam set more firmly.
- Keep simmering until the jam thickens and reaches your desired consistency. To test, place a spoonful of jam on a chilled plate and run your finger through it—if it wrinkles and doesn’t run back together, it’s done.
4. Add Flavors (Optional)
- Stir in the cinnamon and vanilla extract for a hint of spice and depth of flavor. Taste and adjust sweetness if needed by adding more sugar or lemon juice.
5. Fill and Seal the Jars
- Sterilize your jars and lids by boiling them in water for 10 minutes.
- Ladle the hot jam into the jars, leaving about 1/4 inch of headspace.
- Wipe the rims clean, place the lids on, and screw the rings on snugly.
6. Process the Jars (Optional)
- To make the jam shelf-stable, process the jars in a boiling water bath for 10 minutes. Ensure the jars are fully submerged.
- Remove the jars and let them cool completely on a towel or rack.
Storage:
- Properly sealed jars can be stored in a cool, dark place for up to 1 year.
- Once opened, refrigerate and consume within 2-3 weeks.
Serving Suggestions:
- Spread on toast, muffins, or pancakes for a delicious breakfast.
- Swirl into yogurt, oatmeal, or smoothie bowls for a fruity boost.
- Use as a filling for cakes, tarts, or thumbprint cookies.
- Pair with cheese and crackers for a sweet-and-savory snack.
Tips for Success:
- Use fresh, ripe blueberries for the best flavor and sweetness. If you’re using frozen blueberries, make sure to thaw and drain them well to avoid excess water in your jam.
- For a smoother texture, you can strain the jam to remove any skins or seeds.
- Experiment by adding other fruits like raspberries or blackberries for a mixed-berry jam.
This luscious blueberry jam is the perfect way to preserve the taste of summer and bring a touch of sunshine to your pantry all year long!
