Looking for a small batch blackberry jam without pectin?

This easy seedless blackberry jam recipe is made with fresh summer berries, real sugar, a touch of vanilla, and a splash of bourbon for depth.

It’s perfect for water bath canning and full of bold berry flavor with no artificial thickeners. Whether you're a beginner or seasoned canner, this homemade jam brings the taste of summer to your pantry... no fancy tools or acreage required.

Blackberry season hits different.

There’s something wild about it... stained fingertips, scratched-up arms, the way those plump berries give just enough resistance before they drop into your pail. It’s messy and honest and completely worth it.

This jam is that moment in a jar. Sweet, tart, bold, and kissed with a splash of bourbon and vanilla that makes it feel just a little grown up. It’s the kind you eat off a spoon before it’s even cool. The kind you hide in the back of the pantry so your kids don’t find it.

Ingredients for Seedless Blackberry Jam

Blackberries. The heart and soul of this jam... bold, juicy, and just tart enough to keep things interesting. Fresh-picked is ideal, but frozen works too in a pinch.

Sugar. Sweetens and thickens the jam naturally, balancing blackberries' tang. Also essential for that rich jammy texture.

Lemon Juice. Brightens the flavors. It also helps the natural pectin in the blackberries do its job and brings balance to the sweet.

Vanilla Extract. Adds warmth and depth, rounding out the fruit’s natural sharpness. It’s subtle, but you’ll miss it if it’s not there.

Bourbon. Optional, but highly recommended. It lends an oaky caramel note that plays beautifully with blackberries. No bite, just background magic.

Butter. Just a little to keep the foam down and give your jam a silky finish. Makes the stirring less messy and the results more luxe.

How to Make Blackberry Jam with No Pectin

Prep Your Jars. Wash jars, lids, and bands. Keep jars hot until ready to use. Set up your water bath canner and bring it to a simmer.

Strain (Optional). If you prefer a smoother, seedless jam, mash and warm the fresh berries slightly then run them though a food mill to remove most of the seeds. Return the pulp to the pot.

Cook the Berries. In a large pot, combine blackberries and sugar. Stir over medium heat until the sugar dissolves. Let it come to a rolling boil.

Boil Hard. Add lemon juice. Bring to a full, rolling boil that can’t be stirred down. Cook, stirring often, until the jam thickens... about 15–20 minutes.

You’ll know it’s ready when it sheets off the spoon or reaches 220°F on a thermometer.

Add Flavor. Once it’s thickened, remove from heat and stir in the bourbon and vanilla.

Jar It Up. Ladle hot jam into warm jars, leaving ¼-inch headspace. Wipe rims, apply lids, and screw on bands fingertip-tight.

Water Bath. Process in boiling water for 10 minutes (adjust for altitude). Let jars cool undisturbed for 12–24 hours. Check seals before storing.

Pro Tips

Too many seeds? Use the food mill or mash and strain half the berries before cooking.

No bourbon? Swap it for a little cinnamon or skip it entirely, still amazing.

Short on berries? Make a mixed berry jam with blackberries & raspberries or blueberries.

Use a tall pot! Blackberries are notorious for foaming like mad once they hit a rolling boil. Be sure your vessel is tall enough and keep an eye on it constantly!

This no-pectin blackberry jam is bold, silky, and just sweet enough... with rich berry flavor, a kiss of vanilla, and a splash of bourbon for grown-up depth. It’s small batch, seed-optional, and water bath safe. No commercial pectin, no thickeners, just real ingredients and slow-simmered magic in a jar. Perfect for canning beginners or seasoned preservers with a blackberry haul to tame.

Ingredients

6 Cups Blackberries (fresh is best, frozen can be completely thawed first)
3 Cups Pure Cane Sugar (more or less to taste)
3 Tablespoons Lemon Juice
½ teaspoon Vanilla Extract
½ teaspoon Bourbon (optional)

Instructions

Prep Your Gear. Wash half-pint jars, lids, and bands in hot soapy water. Set up your water bath canner with a rack and start heating the water to a simmer. Place jars in canner to keep jars warm until you’re ready to fill.
De-Seed the Berries (optional). If you prefer seedless jam, warm the berries slightly, then run them through a food mill or mesh strainer. Return the smooth pulp to your pot. (You can also go half-seedless if you like a little texture.)
Cook the Jam. Add blackberries (or pulp) and sugar to a large, tall pot. Stir over medium heat until the sugar dissolves. Add lemon juice. Bring it to a hard, rolling boil, the kind that doesn’t stop when you stir. Boil 15–20 minutes, stirring often, until it thickens. Use the spoon “sheeting” test or a thermometer (220°F at sea level) to check doneness.
Flavor It. Remove from heat. Stir in vanilla and bourbon. Add a small pat of butter to reduce foam if needed.
Jar It Up. Ladle the hot jam into warm jars, leaving ¼-inch headspace. Wipe rims clean, add lids and bands, fingertip-tight.
Water Bath Can It. Process jars in boiling water for 10 minutes, adjusting for your altitude (see below). When time’s up, turn off the heat, let jars rest 5 minutes in the canner, then remove. Let cool undisturbed 12–24 hours. Check seals. Label and store in a cool, dark pantry.

Notes

Altitude Adjustments:

0–1,000 ft: 10 minutes
1,001–3,000 ft: 15 minutes
3,001–6,000 ft: 20 minutes
6,001–8,000 ft: 25 minutes
8,001–10,000 ft: 30 minutes
Foam Monster? Blackberries foam up like mad... use a tall pot, stir frequently, and don’t walk away. Butter helps tame it at the end.

Seed Texture: Want some bite? Skip the food mill. Want smooth jam? Run all or half through a food mill or strainer.
Jam Not Thickening? Simmer longer. It thickens as it cools. If it’s still loose the next day, it’ll make a gorgeous syrup.
Short on berries? Combine with blueberries or raspberries—just keep the total fruit ratio the same.

I thought I'd share my experience making this batch. I'm a neophyte in jam making - this is maybe the fourth batch or so that I've made to date - so I'm still learning as I go.

1) I made it pretty much as described - 3 cups of sugar to 6 cups of blackberries, plus 3 tablespoons of lemon juice. I used frozen blackberries, and found that two 16-oz bags worked out almost exactly to six cups. I thawed them and put them through a food mill. I did add the grated zest of the two lemons I juiced for the lemon juice, as I don't like to waste it.

2) My yield was about two and one half cups of jam. I'd be interested to hear how much of a yield other peope got, as I suspect that I cooked mine down a bit too much.

3) Don't be concerned about this recipe lacking added pectin! It really doesn't need any. Cooking the ingredients on a medium-low boil for a long enough time really does get it to the point where it will set. That's where my own lack of experience bit me once again.

In my previous batches of jam, I've tended to not cook it long enough, and so it wouldn't set. This time, I was careful to do sheeting tests, using both the chilled spoon and the chilled plate methods. But I'm not good at interpreting the results of either method, and so I ended up with a final result that's too hard to spread easily; sort of case-hardened jam. I've had both this problem and altogether failures of my jam to set in the past, so I tried giving my too-hard blackberry jam from this batch 15-20 seconds in the microwave before using it, and this does soften it up adequately, although it must be done every time I'm going to have some. But it is a workable salvage for an overcooked jam, and I have to hope that eventually, I'll get better at recognizing when to turn off the heat and start ladling into the jars.
