Ingredients
To create this heavenly Blueberry Jam, you’ll need the following fresh and colorful ingredients:
- 6 ½ cups fresh blueberries: Bursting with juicy goodness, these plump berries are the star of the show.
- 4 ½ cups granulated sugar: This sweet, crystalline ingredient adds the right amount of sweetness to balance the tartness of the blueberries.
- 1 box (1.75 oz) Sure-Jell less sugar pectin: A kitchen essential that helps the jam set while allowing for a more natural taste.
- ½ tsp unsalted butter: This creamy addition helps to reduce foaming, resulting in a clearer jam.
- 1 tsp lemon zest: The aromatic zest adds a refreshing brightness, enhancing the overall flavor profile.
Step-by-Step Directions
Prepare the blueberries
Start by gently crushing your fresh blueberries with a masher until they are broken down but still retain some texture. It’s important to avoid pureeing them completely, as you want small bits of berries for a delightful jam consistency. Measure out your sugar into a separate bowl, so it’s readily available when needed.
Cook the blueberries
In a heavy-bottom kettle, combine the crushed blueberries, Sure-Jell, butter, and lemon zest. Heat the mixture over medium heat, stirring until everything is well combined. Keep an eye on it and allow the mixture to come to a rolling boil — the kind that doesn’t stop bubbling when stirred. This usually takes about 8-12 minutes.
Add sugar and boil
Once your blueberry mixture is at a rolling boil, it’s time to add in the granulated sugar. Stir well and let the mixture come back to a rolling boil. Allow it to boil for exactly 1 minute to ensure the sugar is fully dissolved and integrated.
Jar the jam
Get your sterilized jars ready! Using a ladle, carefully pour the blueberry jam into the jars, leaving about ¼ inch of headspace. Wipe the rims of the jars with a clean cloth to remove any excess jam that may prevent a proper seal. Place your prepared lids and rings on each jar, tightening them to fingertip tightness.
Water bath the jars
Now it’s time to can your jam! Lower the filled jars into a prepared water bath canner fitted with a rack. Bring the water to a boil and let it boil for about 10 minutes. Afterward, remove the jars and place them on a cooling rack. You should hear a satisfying pop as the jars seal — a sound of success! Allow them to cool for at least 12 hours before checking the seals.

- Use ripe, fresh blueberries for the best flavor.

- For a little extra zing, consider adding a pinch of cinnamon or a splash of vanilla extract to the mixture as it cooks.
