The biscuit is my Paleo sweet potato biscuit recipe.  I did make two changes.  I used cashews instead of walnuts and I used white sweet potatoes versus garnet.

    I like that there is very little honey in this recipe. So many jams are far too sweet for me and end up making me sick. I’ll try this but I’m a little afraid of the bovine gelatin.

      Yes! I was looking for a low sugar preserve or jam recipe and I love this!
      Don’t be afraid of gelatin, it’s super easy to work with and you can even correct constancy after its set. I use gelatin pretty often to make homemade “jello”. It’s good for your nails and bones. And it’s flavorless, it can go in anything!

    Girl, that looks great! Putting it on biscuits puts it over the top. Yum!

    This doesn’t look too hard. I’m definitely going to try this. Thanks for the great idea and the biscuits look so good.

    My dad was diagnosed with adult onset diabetes a couple of years ago and has cut out all sugar. Would this work for him with his diabetes? He loves blackberry jam and we have dewberries (a variety of blackberries) on our ranch and have several bags in my freezer.

      You could easily replace the honey with stevia or, if your berries are sweet enough, skip the sugar altogether.

    I love this recipe. So easy. I use frozen fruit. I’ve tried raspberry and blackberry so far and both were great. I chose to add the honey and vanilla at the same time as the gelatin( after cooking on stovetop) to preserve the nutritional value of the ingredients. Thank you for this recipe:)

      I’m so glad that you enjoyed it Cassandra!

    Instead of using frozen berries could I use fresh berries off the blackberry bushes? I have a boatload of blackberry bushes in my treeline and would rather use them.

        Would fresh strawberries work too?

    This sounds amazing! Must try 1st. Btw. I looked to find your gelatin and it can be found on For those that need to know the product info does indicate that the cattle feed on grain and grass so not 100% grass fed nor neccesarily non gmo since cattle are from Argentina where much gmo grain is grown.

    Working on this recipe right now! Smells amazing. When I added the gelatin, it all chunked up. I have put it in my vitamix to try to dissolve. Did I do something wrong? Using Great Lakes gelatin.

      Did you add it when the ingredients were warm? I’ve noticed if it hot when I put it in, it will chunk up.

    do you have to dissolve the gelaten in a liquid first

    1. Kelly Bejelly November 27, 2018 at 10:43 am

      Yes, David I would recommend doing that.
