Store-bought blackberry jam is often too sweet and doesn’t have that fresh berry flavor. That’s why I love making this Homemade Blackberry Jam whenever blackberries are in season.

It comes together with simple ingredients and tastes so much better than anything from the store. Spread it on toast, biscuits, or pancakes for an easy homemade treat.

If you’ve picked more blackberries than you know what to do with, this recipe is the perfect solution for you.

Ingredients

Fresh Blackberries
Granulated Sugar
Fresh Lemon Juice

Ingredient Notes

Fresh blackberries produce the best flavor, but frozen berries work well too. Thaw them first.
Adjust the sugar slightly depending on how sweet your berries are.
Fresh lemon juice is preferred over bottled for the freshest taste.

Step-by-Step Instructions

Step 1: Wash the Blackberries

Rinse the berries thoroughly under cold water and remove any stems or damaged fruit. Drain well.

Step 2: Mash the Berries

Add the blackberries to a large saucepan. Gently mash them with a potato masher until mostly broken down while leaving a few small chunks for texture.

Step 3: Add Sugar and Lemon Juice

Stir in the sugar and freshly squeezed lemon juice until everything is evenly combined.

Step 4: Cook the Jam

Place the saucepan over medium heat.

Bring the mixture to a gentle boil, stirring frequently to prevent sticking.

Continue cooking for about 20–30 minutes, allowing the mixture to thicken naturally.

Step 5: Check the Consistency

Place a small spoonful on a chilled plate.

Wait 30 seconds, then push it with your finger.

If it wrinkles and holds its shape, the jam is ready.

If not, continue cooking for another few minutes and test again.

Step 6: Remove Foam

If foam forms on top, skim it off with a spoon for a smoother, clearer jam.

Step 7: Cool and Store

Allow the jam to cool slightly before transferring it into clean sterilized jars.

Let cool completely before sealing.

Refrigerate until ready to enjoy.
