Add blueberries, cane sugar, and lemon juice to a medium pot. Cook over medium heat until the sugar has dissolved. Turn the heat to high and boil for 1 to 2 minutes, stirring occasionally.
Turn the heat back down to medium/low and simmer for about 10 minutes or until the consistency is thick. Transfer to a glass jar and let cool to room temperature.
Store in the fridge for up to 2 weeks.
Notes
Tips
You can use fresh or frozen blueberries for preserves. Whatever you have on hand is fine!
Once the blueberries start to bubble, you can squish them with your spatula to break them up easier.
If you want smaller fruit pieces, you can cut up the blueberries beforehand and you'll end up with a smoother consistency.
