Ingredients
Scale
- 4 cups fresh or frozen blueberries
- 2 cups granulated sugar
- 2 tablespoons lemon juice
Instructions
- Wash the blueberries and remove any stems.
- In a large pot or Dutch oven, combine the blueberries, sugar, and lemon juice.
- Stir the mixture over medium heat until the sugar dissolves.
- Bring the mixture to a boil, then reduce the heat and simmer, stirring occasionally, for 20-30 minutes, or until the jam thickens.
- To test for thickness, place a small dollop of jam on a cold plate. If it sets and doesn’t run, it is ready.
- Skim off any foam that rises to the surface.
- Carefully ladle the hot jam into sterilized jars, leaving about 1/4 inch of headspace.
- Wipe the rims of the jars clean and place lids and rings on tightly.
- Process the jars in a boiling water bath for 10 minutes (adjust time for altitude).
- Remove the jars from the water bath and let them cool completely on a wire rack. The lids should seal as they cool.
Notes
- You can adjust the amount of sugar to your preference.
- For a smoother jam, you can mash some of the blueberries before cooking.
- Store unopened jars of jam in a cool, dark place for up to a year.
- Once opened, store the jam in the refrigerator for up to 3-4 weeks.
