Seedless Blackberry Jam Made Simple | Baking a Moment

I made jam!


This was a first for me.  I always thought the idea of canning and preserving seemed so complicated, and scary, and I was too intimidated to make any attempt.  Daunted!

Well, sometimes the most wonderful things have a way of just falling into your lap, and before you know it, you’re knee deep in a water bath, sterilizing jars…


We enjoyed our last summer shore weekend this past, and it was so nice to relax, enjoy a little sun and cool breeze, and catch up with family for a few days.  (And my big boy lost his first tooth!  Please excuse my hollering like a lunatic…)

My brother- and sister-in-law showed up with a mahoosive bucket of blackberries they had picked at a local farm.  (Remember just a couple of weeks ago, I was griping about how expensive blackberries are in Pa?  What a stroke of luck!)  Many of them went straight into our hungry mouths, but by the end of the weekend there were still over two pounds remaining.  Mr. Allie and I bounced a few ideas around for what I could do with them, but I soon realized there were just way too many to simply bake into a recipe.

And what better way to repay my dear in-laws for their blackberry generosity, than to offer them a jar or two of homemade preserves at our next holiday gathering?

There’s a lot of info on home canning out there on the interwebs, so I spent a solid morning just familiarizing myself with the process.  I decided to go the non-pectin route.  Just seemed a little more rustic to me.  Plus, I didn’t feel like making a trip to the store.  Truth.

I learned that you can be super specific about it, or you can be more relaxed, and add sugar/flavor enhancers by taste and feel.  Contrary to my uber-perfectionist, Virgo (read: anal) tendencies, I decided to just go with the flow.  Worrying about sterilization and sanitation is enough of a fuss for me, being a first-timer and all.

Before I launch into the nitty-gritty, let me put your mind at ease.  Jam, or preserves, are nothing more than reduced and thickened fruit.  If you can make a sauce, you’ve got jam in the bag.  And if you don’t mind keeping it in the fridge, you don’t even have to bother with the boiling and sterilizing.  I wanted to go ahead and take a proper crack at it, so here’s how it all went down.  

After giving them a cool-water rinse, I macerated the berries in sugar overnight, sweetening them and helping them to give up a lot of juice.

Macerated Blackberries

I didn’t really bother to pick over the berries, removing stems/leaves, etc., because I knew I’d be straining them anyway.  I’m not a fan of seedy jam so I took the extra step.  Any other kind of fruit, and I would have loved big chunks, but I just find those big blackberry seeds to be super-annoying.  No thanks.

Speaking of de-seeding blackberries, I remember receiving a food-mill as a wedding gift, oh, about an eternity or so ago.  This would have been the perfect time to crack it out, but here’s a glimpse into our mad basement organization skillz:


Um, ya.  Maybe I’ll just use my seive, mmmmkay?

Back to jam.  I let the berries soften up over medium heat, and then I strained them.  It was a tedious process, but don’t let that deter you from jam-making.  If not for this step, the whole business would have been a snap.  And after a little while it became kinda meditative…  Scoop in soft berries, push, push, swirl… push, push, swirl… the ladle worked great for this.

DeSeeding Blackberries

I submerged the jars in boiling water for 10 minutes while all this was going on.  (Keep them warm so they don’t crack when the hot jam goes in!)

Once the blackberries were de-seeded, I just whacked the puree on the stove and (slowly) brought it up to a bubble, stirring.  I also threw the lids into some simmering water to soften up that ring of gummy gunk that makes the seal airtight.

How to Make Blackberry Jam

A squeeze of fresh lime, a quick taste for sweetness and maybe a little more sugar or citrus, and once it looked dark, shiny, and thickened, it was ladled into hot, sterilized jars.

How to Make Blackberry Jam

Wipe around the rim, lids go on, and the jars are placed back in the big pot of water and boiled for 10 minutes.

Once they’ve cooled completely, you can check the seals.  If the “button” pops up and down, then they didn’t seal properly.  It’s ok though.  Those’ll keep in the fridge for a couple weeks.  But if it’s a tight seal, they’ll keep in a cupboard for MONTHS!  Perfect homemade gift!

This wasn’t so hard.  I’d do it again.  As a matter of fact, I’ve got an itch to make a big batch of tomato jam… so keep an eye out for another possible canning post, guys.  😉

And, I’ve got a scrumptious recipe up my sleeve to utilize these sweet and luscious preserves!  So stay tuned!  I’m totally psyched to get baking again!

    Any leftover jam (that does not fill a jar within 1/4" of the rim) can be kept, refrigerated, for 2-3 weeks.

    Jam that has been properly processed (the button on the lid should not pop up and down) can keep in a cupboard for several months.

    PS- I didn’t buy any special equipment, other than the jars.  A lot of websites/stores will make you think that you need a whole arsenal of task-specific canning equipment, but I just was not interested in making the investment (of time, storage space, or money).  A well-stocked kitchen already includes a stock pot and a pair of tongs, and mine’s no exception.  I’m sure a wide-mouth funnel, pair of canning tongs, magnetized lid-grabber, and jar-lifter-outer-basket would have been nice, but unless you think you’ll be doing a buttload of canning in the future, I think you’ll get by ok without.

    Have you ever tried canning?  Do you enjoy it?  Are you a pectin-using, recipe following type, or do you just taste and adjust?  Have you ever done any interesting flavor combos?  (I toyed around with the idea of adding a little gin to my blackberry-lime concoction.)  Or are you just completely intimidated by the whole idea?    I have to say, that for me, once I gave it a go I realized it’s not so scary.  Just keep everything warm and boil it well and you’re golden.

    How do you like to use fruit preserves in your baking?  Would love to hear your thoughts/ideas; as always, your comments are the bright spot in my day!  😉
