Jam, Jelly, and Preserves—What’s the Difference?

- Jam uses mashed fruit and has a soft, spreadable texture.
- Preserves contain whole or large pieces of fruit.
This recipe can be jam or preserves—just mash the blueberries more for jam, or leave them mostly whole for blueberry preserves.
Ingredients Notes

- Blueberries: Fresh are best, but frozen also work well. If using fresh, rinse thoroughly, remove stems and debris, and let dry. If using frozen, thaw first to reduce extra water.
- Sugar: Balances the berries’ tartness and helps preserve the jam.
- Lemon Juice: Helps the jam set naturally with its natural pectin.
- Lemon Zest : Optional, but highly recommend for a little extra zing and freshness.
How to Make Blueberry Jam without Pectin
This section shows you how to make the recipe with step-by-step photos and instructions. For the full printable recipe, see the recipe card below.
Step 1: Combine blueberries, sugar, lemon juice, and lemon zest in a large saucepan. Lightly mash berries with a potato masher, if desired, for a smoother texture. Stir continuously while bringing to a gentle boil over medium heat.

Step 2: Reduce heat to medium-low and simmer uncovered for 10–14 minutes, stirring occasionally, until thickened and between 210–220°F—or until it passes the chilled plate test.
Chilled Plate Test
No thermometer? No problem. Place a small plate in the freezer while the jam cooks. Spoon a little jam onto the plate, return it to the freezer for 1 minute, then run your finger through the jam. If it wrinkles and holds the line, it’s ready. If not, cook a few minutes longer and test again.

Step 3: Remove the pot from the heat. Let rest 5 minutes before carefully spooning jam into two 8-ounce jars or one 16-ounce jar. Leave the hot jars uncovered until the jam cools to room temperature.

Storage
Refrigerate in an airtight container for up to 3 weeks.
Freeze for up to 3 months. Leave ½ inch of space at the top of the jar to allow for expansion. Thaw overnight in the fridge.
Homemade jam can be enjoyed once it’s cool, but it fully sets after 24 hours in the refrigerator.
A Quick Note on Canning
This recipe is not intended for canning. I don’t have personal experience with canning methods, so I recommend storing this jam in the fridge or freezer for safety. If you’d like to make a shelf-stable version, please consult a trusted canning resource.

Tips for Success
- Stir continuously while bringing to a boil to prevent sticking.
- Use an immersion blender if you prefer smoother jam.
- Let jam cool fully before sealing jars to avoid trapped moisture.
- Don’t skip lemon juice—it helps the jam thicken naturally without pectin.
Additions and variations
- Add a pinch of cinnamon or nutmeg for a warmth.
- Stir in a splash of vanilla extract after cooking for extra depth.
- Mix in raspberries or blackberries for a berry blend
- Reduce sugar slightly if you prefer a more tart flavor.
