This easy, delicious blueberry jam recipe is made with 4 ingredients: blueberries, sugar, lemons, and honey! The honey is used to replace some of the sugar, and the lemon zest + juice perfectly balance out the sweetness of the jam. You can spread it on some toast, top your yogurt, or stir it into your matcha lattes!
In a large saucepan, stir together all of your ingredients: 2 pounds blueberries, 1 cup granulated sugar, 3 tablespoons honey, 1 tablespoon lemon zest, and 3 tablespoons lemon juice.
Turn the heat to medium and stir. Once the blueberries soften, mash them up in the pan. Gently boil for 15-25 minutes, scraping the bottom + sides of the pan often. It will be really liquidy at first, then cook down and thicken.
To test if the jam is done, drag your wooden spatula across the bottom of the pan. If it leaves a clear trail and the jam takes 2-3 seconds to fill in the gap, it's finished! It will continue to thicken while it cools.
Enjoy!

Notes
Want to omit the honey? Replace it with ⅓ cup sugar instead.
Tips:
Use fresh, ripe blueberries! The more ripe, the more flavorful the jam.
Cook the jam in a large, wide pan. I actually like using my sauté pan because it’s super wide and shallow, which helps it cook more evenly compared to a deep pot.
Storage: Homemade blueberry jam can last up to 2 months in the fridge. You can also store it in the freezer and let the jam thaw overnight before using. For long-term storage, you can always can your blueberry jam! It can last for over a year if left unopened.
