Ingredients You’ll Need
Getting started on this Blackberry Jam Recipe means gathering a handful of straightforward, kitchen-friendly ingredients that you’ll likely have or easily find. Each one plays a crucial role, from the sweet tang of sugar to the fresh brightness of lemon juice, helping create a jam that’s perfectly textured, delectably sweet, and full of that lovely blackberry punch.
- 4 cups fresh blackberries: Using fresh berries ensures a deep, natural flavor and vibrant color, but frozen works well if fresh aren’t available.
- 2 cups granulated sugar: This is essential for sweetness and also helps with the jam’s preservation and consistency.
- 1 tablespoon lemon juice: Adds brightness and balances sweetness while helping the jam set properly.
- 1/2 teaspoon vanilla extract (optional): A gentle layer of warmth and depth if you want to take the flavor up a notch.
- 1/4 teaspoon ground cinnamon (optional): For a subtle hint of spice that complements the blackberry’s natural tartness.
How to Make Blackberry Jam Recipe
Step 1: Prepare the Fruit
Start by washing and draining your blackberries if they’re fresh. Then, grab a potato masher or fork to crush them gently, allowing the juices to come out and form the base of your jam. If you prefer a smoother texture, an immersion blender can make quick work of turning those berries into a luscious puree.
Step 2: Combine Ingredients and Cook
In a large saucepan, combine the crushed blackberries, sugar, lemon juice, and if you’re feeling adventurous, the vanilla extract and cinnamon. Give everything a good stir, then place the pan over medium heat and bring the mixture to a simmer. This is where the magic starts, as the sugar dissolves and the flavor starts to concentrate.
Step 3: Simmer and Thicken
Lower the heat to keep the jam at a gentle simmer, stirring frequently to prevent sticking and burning. Let it cook for 25 to 30 minutes, during which time the mixture thickens beautifully. To test if your blackberry jam is ready, drop a spoonful onto a chilled plate and run your finger through it; if it wrinkles and holds its shape, your jam has set!
Step 4: Cool and Store
Once your jam has thickened perfectly, remove it from heat and let it cool for about 10 minutes. Then, pour it into sterilized jars. You can keep the jam fresh by storing it in the refrigerator for up to three weeks, or you can preserve it longer by processing the jars in a boiling water bath for 10 minutes before sealing and cooling completely.
How to Serve Blackberry Jam Recipe
Garnishes
A dollop of freshly whipped cream or a sprinkle of lemon zest on top can beautifully accentuate the rich flavors of your blackberry jam. Fresh mint leaves are also terrific for a pop of color and a refreshing scent that complements the jam’s fruity sweetness.
Side Dishes
This Blackberry Jam Recipe pairs wonderfully with warm buttered toast, flaky croissants, or even as a sweet addition to savory cheese boards. It also makes a delightful swirl stirred into creamy Greek yogurt or oatmeal for a vibrant breakfast boost.
Creative Ways to Present
Why not step outside the jar and try the jam as a glaze on roasted meats or grilled vegetables? It also works beautifully as a filling for thumbprint cookies or layered in parfaits for a stunning appearance and incredible flavor contrast.
Make Ahead and Storage
Storing Leftovers
If you find yourself with extra jam, no worries! Store leftovers in airtight containers in the refrigerator where they will stay fresh for up to three weeks. Be sure to use a clean spoon each time you scoop to avoid contamination.
Freezing
Blackberry jam freezes exceptionally well, making it an easy option for long-term storage. Use freezer-safe containers or jars leaving some headspace for expansion, and thaw the jam overnight in the fridge when you’re ready to enjoy it again.
Reheating
To bring your frozen or refrigerated jam back to a pourable consistency, gently warm it in a small saucepan over low heat. Stir occasionally until it softens, but avoid boiling to keep the fresh flavor intact.
FAQs
Can I use frozen blackberries instead of fresh?
Absolutely! Frozen blackberries are a great substitute if fresh ones are out of season. Just thaw them completely and drain any excess liquid before starting your jam.
How long will homemade blackberry jam last?
If stored in the refrigerator, homemade blackberry jam typically stays fresh for up to three weeks. Properly canned and sealed jars can last up to one year in a cool, dark place.
Do I have to use lemon juice?
Lemon juice isn’t just for flavor; it helps the jam set properly by encouraging gel formation. It also balances sweetness for a more complex taste, so it’s best to include it in your recipe.
What if my jam doesn’t thicken?
If your blackberry jam is too runny after cooking, return it to the stove and simmer longer, stirring constantly. You can also add a small amount of pectin or mashed chia seeds for natural thickening.
Can I skip the vanilla or cinnamon?
Of course! These ingredients are optional and meant to add a subtle depth of flavor. Your basic blackberry jam will still be delicious without them.

Other Ingredients
- 2 cups granulated sugar
- 1 tablespoon lemon juice
- 1/2 teaspoon vanilla extract (optional for extra flavor)
- 1/4 teaspoon ground cinnamon (optional for added warmth)
Instructions
- Prepare the Fruit: Use a potato masher or a fork to crush the blackberries to release their natural juices. For a smoother jam, you may opt to blend the berries briefly with an immersion blender before cooking.
- Cook the Jam: Combine the crushed blackberries, granulated sugar, lemon juice, and optional vanilla extract and cinnamon in a saucepan. Stir well and bring the mixture to a gentle simmer over medium heat.
- Simmer and Thicken: Once simmering, reduce the heat to low and let the jam cook for 25-30 minutes, stirring frequently to prevent sticking and burning. The jam mixture will thicken as it cooks. To test the consistency, place a small spoonful on a cold plate and run your finger through it; if it wrinkles and holds its shape, the jam is ready.

Notes
- Ensure jars are properly sterilized to avoid contamination and extend shelf life.
- Adjust the cooking time slightly if you prefer a runnier or thicker jam.
