A recipe for Simple Blackberry Jam. Simple Blackberry Jam recipe. Simple Blackberry Jam recipe. Hi All! So, I was at my farmer’s market the other day and bought a palette of blackberries. One or two baskets should’ve been enough, but they were so big, sweet, and fresh that day I couldn’t help myself and against my better judgment I bought an entire palette. After devouring a basket on my drive home, passing some out to eager neighbors (sharing is caring), and freezing a few baskets I decided I didn’t need any old plan for the rest, because I had a JAM PLAN (totally nerdy and kind of obscure “Friends” reference). Really though, I decided to make jam, something I’d been meaning to do all summer and just hadn’t gotten around to do. I was stoked!! But before I tell you all about the jam, can I tell you a little something? Powdered gelatin sort of give me the heeby-jeebies. I prefer sheet gelatin. In my mind, powdered gelatin has a funky smell. Am  alone on this? Also, I find that I always get a better consistency when I use sheet gelatin. Again, totally a preference thing. Powdered gelatin works just fine in this recipe, but if you can get your hands on some sheet gelatin (specialty cake/bake shops have them or you can order them online) use that instead, you won’t regret it! I made a basic blackberry jam which I like a little less sweet, so if you want to add more sugar, little by little, by all means please do. Also, if you want an added kick feel free to drop a stick of cinnamon to the mix or a few whole star anise and let the flavors infuse. So Good!

    so lovely! i tried to go blackberry picking, but they were mostly gone so i got raspberries and made some tasty jam with them instead. i agree, i like mine less sweet too. this looks gorgeous, i should head to the store and try this out :-) (totally got the Friends reference btw, haha…)

    Interesting . . . I’ve never used gelatin when making jam; I always use pectin. I’ve never noticed an aroma to it–maybe ’cause it’s plant-based. Great suggestion about the star anise, too–I used some in my blueberry jam earlier this summer, and it’s yummy.

    beautiful blog!

    i am wondering why you use gelatin in your recipe. Blackberries have so much pectin

    in them naturally that they don’t need any thickening agent.

    • Jenny Park Not Specified Not Specified

      Hi Manny! This is very true; blackberries are filled with natural pectin. I like to add a little gelatin because you don’t have to cook the jam down for as long and I prefer the slightly more “gel-like” consistency. You can omit the gelatin and cook the mixture down longer if you prefer. Thanks for reading!

    I love this recipe! If I omit the gelatin, how long should I let it cook down for? Thanks!

  27. Gretchen Not Specified Not Specified

    Hi, made this today . . . something went wrong. It’s too thin. I’m thinking it should have cooked longer.

  28. April Not Specified Not Specified

    Just made and loved! I added chili powder and cinnamon, hoping to use on biscuits OR as a glaze over chicken or pork! Yummy!

  29. Jen Not Specified Not Specified

    What if one is using liquid pectin….can the amounts be the same?

  30. Kristen Not Specified Not Specified

    Can I use pectin instead of gelatin sheets? I really like the sound of this recipe. Thanks so much!

  31. Susan Not Specified Not Specified

    Why do you store the jam you canned in the refrigerator? I store the jam I make in my pantry and really like that I don’t have to take up limited refrigerator space. Thanks.

    I “stumbled upon” your blog and saw the baked egg boat and Blackberry jam. I love everything i see. What a great find you are! I really should put down my phone and get some work done around here, but I don’t feel like it! Think I’ll hang out and browse more recipes!

    I’m new to all this canning and preserving foods as I only started a few years ago. Being from a small (one red light) southern town there actually aren’t many of “my generation” that put in the work and dedication to do this. (I’m only 35) so I have to rely on friends parents and grandparents but mostly the Internet. ….I am very greatly to have found your blog! Thank you so much for helping myself as well as others!
