Sure Jell Low Sugar Blueberry Jam Recipe: Bright Chunky Spread With Pantry Staples

This Sure Jell low-sugar blueberry jam recipe delivers all the bright, fruity flavor of summer without the heavy sweetness—perfect for those watching sugar intake or simply craving a lighter spread.

The secret lies in balancing ripe blueberries with just enough honey or maple syrup, plus a precise pectin measurement that ensures a perfect set without gummy results.

Whether you're canning for long-term storage or making a small batch for immediate use, this recipe delivers professional-quality results with just a few simple ingredients. Let’s get started on creating your own bright, chunky spread.

Ingredients for sure jell low sugar blueberry jam

Pantry staples meet summer's brightest berry—no sugar overload here.

Blueberries are the star, so grab the freshest, firmest you can find—those organic bins at Whole Foods or your local farmers market are perfect. The pectin is non-negotiable: Sure Jell Low Sugar gives that perfect set without gummy texture. For honey, local varieties add depth, but any raw honey works. Maple syrup? Grade B has that rich, caramel-like flavor that elevates everything. Lemon juice should be freshly squeezed—bottled just won’t cut it for that bright tang. And that olive oil? It’s not just for cooking—tossing the berries in it first helps release their juices beautifully.

No honey? Agave nectar works 1:1, though it lacks the floral notes. Skip the maple syrup? Extra honey or a splash of apple cider vinegar keeps things balanced. Running low on lemon juice? Lime juice at half the amount gives a zesty twist. The sugar is truly optional—this jam shines with just the honey and maple, but if you’re serving to kids or need extra sweetness, granulated sugar does the trick. For vanilla, imitation won’t do—pure extract is worth the splurge here. And if you’re feeling fancy, a pinch of cinnamon in the final stir adds warmth.

This jam keeps for 3 weeks in the fridge, sealed tightly in a clean jar. For long-term storage, freeze portions in ice cube trays—just thaw overnight in the fridge. The texture gets even better after a day or two as flavors meld. Label those jars with dates, because once you taste this, you’ll be making it all season long. And trust me, one batch won’t last—it disappears faster than you can say ‘chunky blueberry jam’ on toast.

Step-by-step instructions for Sure Jell low sugar blueberry jam

Here's how to craft a vibrant, chunky blueberry jam that balances sweetness with tangy brightness—every step ensures perfect texture and flavor.

Transfer the 4 cups fresh blueberries to a large mixing bowl. I like to gently press each berry with my fingers to release some of the juices—this jumpstarts the flavor extraction and prevents a thin final product. Add the 1 tablespoon extra-virgin olive oil and toss until every berry is evenly coated. The oil creates a delicate barrier that helps maintain those beautiful fruit chunks while preventing excessive gelling.

In a separate small bowl, whisk together the 0.5 cup raw honey, 0.25 cup pure maple syrup, 0.25 cup fresh lemon juice, 0.25 cup granulated sugar, and 1 teaspoon vanilla extract. This liquid mixture is the flavor foundation of your jam—don't skip the vanilla, as it adds depth that complements the blueberry's tartness. The sugar helps balance the natural acidity of the lemon juice while contributing to the jam's set.

Transfer the blueberry mixture to a 4-quart heavy-bottomed pot—I prefer stainless steel for even heat distribution. Add the prepared liquid ingredients and stir gently to combine. Place the pot over medium-high heat and bring the mixture to a rolling boil, which should take about 5-7 minutes. You'll see bubbles form along the edges first, then gradually cover the entire surface.

Once boiling vigorously, reduce the heat to medium and let it cook uncovered for 10-12 minutes. Stir occasionally to prevent sticking, but avoid constant stirring—this can break down the fruit and make the jam too smooth. You're looking for a point where the mixture thickens noticeably and begins to coat the back of a spoon. Here's the thing—if it's not thickening after 12 minutes, you'll need to adjust the pectin or sugar slightly next time, but this recipe is designed to work perfectly with these amounts.

While the jam simmers, sprinkle the 0.33 ounce Sure Jell low sugar pectin evenly over the surface. Let it sit for 30 seconds without stirring—this allows the pectin particles to fully hydrate. Then stir vigorously for 1 full minute to ensure complete dissolution. Return the heat to medium-high and bring the mixture back to a full rolling boil for 1 minute, stirring constantly.

This is the moment that matters: remove the pot from heat immediately. The jam should now be thick enough to mound slightly when dropped from a spoon, but still glisten with moisture. To test for doneness, place a small spoonful on a chilled plate and refrigerate for 2 minutes. When you run your finger through it, the jam should wrinkle slightly but not be stiff. If it's too runny, return it to low heat for 1-2 minutes more and retest. If it's too thick, you can thin it slightly with a few drops of water or lemon juice.

Transfer the hot jam to sterilized 8-ounce jars, filling each to within ¼ inch of the rim. Wipe the rims clean with a damp cloth to ensure proper sealing. Place the lids on the jars and process in a water bath canner for 10 minutes—this step is critical for shelf stability. The jars should seal with a satisfying "ping" sound as they cool. If any don't seal properly, refrigerate those jars and use them within 2 weeks.

Let the sealed jars cool completely at room temperature, then store in a cool, dark place. The jam will continue to develop deeper flavors over the next 24 hours, so I always make it a day ahead if possible. This waiting period allows the flavors to meld beautifully, resulting in a jam that's far more complex than if you ate it immediately. The final product should be vibrant purple with visible blueberry chunks, a perfect balance of sweet and tart, and a texture that's thick but still spreadable.

Pro cooking tips for this recipe

Pectin Timing Matters

The key to perfect jam texture lies in the 30-second rest you give the Sure Jell Low Sugar Pectin before stirring. This pause allows the pectin particles to fully hydrate, ensuring they activate uniformly during the boil.

I’ve ruined batches by stirring immediately—always follow this rule. The pectin needs that brief moment to bloom properly, or your jam will turn out either too thin or gummy. 💡

Heat Control Secrets

Use medium-high heat to reach the initial boil, then immediately reduce to medium once boiling. This prevents scorching while maintaining even cooking. I’ve found that stainless steel pots distribute heat most evenly—avoid aluminum if possible, as it can cause hot spots.

The extended 10-12 minute simmer at medium heat is what develops the jam’s depth without burning the fruit.

Testing Doneness Properly

The plate test is your best friend here. After removing the jam from heat, spoon a small amount onto a chilled plate and refrigerate for exactly 2 minutes.

When you run your finger through it, it should wrinkle slightly but still feel slightly sticky—not stiff like jelly, not runny like syrup. This indicates perfect set. I’ve seen home cooks overcook jam just because they didn’t test properly—don’t make that mistake!

Lemon Juice’s Dual Role

The 0.25 cup lemon juice serves two purposes: it acts as an acidifier (critical for pectin activation) and brightens the blueberry flavor. Never substitute bottled juice—fresh lemon juice contains natural enzymes that enhance flavor development.

If your lemons are particularly tart, you can reduce to 0.2 cup, but don’t go below that or your jam may not set properly. 🍋

Sterilization Shortcuts

For jars, I recommend running them through a 200°F oven for 10 minutes before filling—this kills bacteria and ensures proper seals. If you’re short on time, boil lids in water for 5 minutes instead.

The key is cleanliness: any residue on jar rims can prevent sealing. I keep a dedicated jar rack and sterilize it alongside the jars to maintain a clean workspace.

Flavor Development Wait

Resist the urge to eat your jam immediately! The flavors deepen significantly after 24 hours of resting. During this time, the fruit softens further, the sweetness mellows, and the vanilla infuses completely.

I’ve tasted jam straight from the jar and again after 24 hours—the difference is night and day. This waiting period is what transforms good jam into exceptional jam. ✨
