Instructions
Cooking Blueberries
Add Blueberries, sugar, lemon juice, and vanilla extract into a big pot.
Bring to a boil over medium heat. Stir occasionally with a wooden spoon or spatula.
Sterilize glass jars
Sterilize glass jars by placing them right side up in a pot with boiling water. Water should be an inch above the top of the jars. Bring the water back to a boil (adding the glass jars will drop the water temperature a bit) over high heat.
Once the water reaches a full boil, start your timer. Let the jars in the boiling water for 10 minutes. Then, carefully take them out of the water bath and let them dry on a clean kitchen towel.
Checking consistency
Check the consistency of the preserves after 40 minutes. To test whether the blueberry preserves are ready, use a spoon and put some of the preserves on a small plate. Let it cool (you can put it in the fridge to speed up the process) and then run a finger through it. If there is a clear path and the preserves don't run back together, it's done!
Remove pot from the heat and transfer the preserves to clear glass jars. A funnel works great for that.
Cover the glass jars and allow the preserves to cool completely before you put them in the refrigerator. The preserves will keep for 3-4 months in the fridge.
