Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

• 4 cups fresh blueberries

• 1 ½ cups granulated sugar

• 1 Tablespoon lemon juice

• ½ teaspoon lemon zest

Directions

1. In a large saucepan, stir together the blueberries, sugar, lemon juice, and optional lemon zest. If you prefer a smoother texture, lightly mash the blueberries with a potato masher to your liking.

2. Stir continuously while bringing the mixture to a gentle boil over medium heat.

3. Once boiling, reduce the heat to medium-low. Let the mixture simmer uncovered for 10–14 minutes, stirring occasionally. It will thicken and reach 210–220°F or pass the plate test (see tip below).

4. Remove from heat and let the jam rest for 5 minutes. It will continue to thicken as it cools.

5. Carefully spoon the jam into clean jars, leaving the lids off. Allow the jam to cool completely before sealing.

6. Store in the fridge for up to 2 weeks or freeze for longer storage.

Plate Test Tip: If you don’t have a thermometer, use the plate test to check the consistency. Place a plate in the freezer while cooking the jam. Once the jam is ready, spoon a small amount onto the chilled plate and return it to the freezer for 1 minute. Run your finger through the jam—if it wrinkles slightly and holds its line, it’s done. If the jam is still very liquidy, continue cooking and test again in a few minutes.
