Place a small dish in the freezer to use for testing the jam.

In a large deep skillet, add blueberries, sugar, and lemon juice. Bring to a rolling boil, stirring often. Once boiling, cook until it thickens, about 10 minutes.

When it seems thick enough, take your plate out of the freezer. Put a small spoonful of the jam onto the plate and let sit for 30 seconds. Tilt it. If it slides too fast, keep cooking in 1-2 minute increments. If it moves slow, it is done.

Transfer to a heat-proof container. Cool to room temperature. If not canning, use within 2 weeks. Once opened, store in the refrigerator.

Place a clean 6-8 ounce glass mason jar and lid pieces into a large pot of boiling water deep enough for the jar to be completely submerged in water. Once the water is boiling, leave the jar in there until ready to use.

Remove the jar and lids from water and drain out all of the water from the jar. Keep the water boiling.

Transfer the finished jam to the jar. Wipe excess jam off the rim so it will seal properly. Add the lid. You may want to use an oven mitt so you can hold the jar still.

Place sealed jar back into the boiling water and boil for 15 minutes. Make sure it is submerged in the water. Remove from the water and let dry on a heat-resistant surface for 18-24 hours.

Once cool, press down on the lid. If it stays down, it is sealed. If it pops back up, put in the refrigerator and use within two weeks.
