Ingredients
Scale
- 4 cups fresh blueberries (or thawed frozen blueberries)
- 1½ cups granulated sugar
- 2 tablespoons fresh lemon juice
- 1 teaspoon lemon zest (optional)
- Splash of water (if needed)
Instructions
- Rinse and sort the blueberries, removing any stems or overripe berries.
- Add blueberries, sugar, lemon juice, and zest to a large saucepan. Let sit 5–10 minutes.
- Heat over medium, stirring frequently, until mixture begins to boil and berries release juice.
- Reduce heat and simmer 20–30 minutes, stirring often. Mash berries slightly for texture.
- Test for set using the cold plate method. When ready, remove from heat.
- Spoon hot jam into sterilized jars, leaving ¼-inch headspace. Seal and cool.
- Store in the fridge for short term or process in a water bath for long-term storage.
Notes
- If using frozen berries, drain well and increase cooking time slightly.
- Add a pinch of cinnamon or vanilla extract for a flavor twist.
- Don’t skip the lemon juice — it helps the jam set and enhances the flavor.
- Use a wide saucepan for faster evaporation and better consistency.
