A beautiful homemade jam is one of life’s simple pleasures, especially when spread over a warm slice of fresh buttered bread. Many people these days are eating more healthy and looking for “clean recipes” to prepare at home. As more information about sugar and its harmful effects are coming to light, there has been a push to reduce sugar consumption.
This is not a raw chia seed jam like so many out there. For convenience, it uses frozen blueberries which are simmered to achieve this beautiful color. But don’t worry, it’s not a long and involved process like making real jams and jellies – it just takes a few minutes. I use my blender to smooth out the consistency of the blueberries and to help thicken the jam.
My sugar-free blueberry chia seed jam recipe has no added sugar and uses chia seeds for their gelling ability and thickening power instead of excess sugar or added pectin. It’s one of three sugar free jelly or jam recipes I have on the blog. My keto raspberry jam tastes just like fresh raspberries and the low carb sugar free strawberry jam resembles a freezer jam in taste. Both use gelatin to thicken.
How to Make Sugar-Free Jam With Chia Seeds
Chia seed jam is easy one of the easiest jams to make. Using pureed fresh ripe fruit or cooked fruit will vary the intensity of color and flavor. A little lemon juice helps acidify the jam preventing spoilage. Use only enough of your favorite sweetener to give the chia seed jam a nice sweet taste. Grind the chia seeds for a smoother jam or keep them whole for some texture. I find that I have to use more chia seeds if I grind them.
How to Make Sugar-free Blueberry Jam
Honestly, blueberries contain enough natural sugar and pectin that you can simply cook them down to make a jam. I used to do this for my children. The problem for those following a reduced sugar and low carb diet is that this concentrates the sugars resulting in a higher sugar product per serving.
To make this sugar-free blueberry jam and keep carbs low, cook the blueberries until they soften and burst. Add low carb sweetener to taste. The most common sweeteners are Erythritol blends, xylitol, and stevia. Put the cooked blueberries in a blender to break up the skins. Pour the fruit puree into a jar, add chia seeds and stir. Let the jam sit overnight in the fridge to give the chia seeds time to expand and gel.
How Long Does Sugar-free Jam Last?
This recipe calls for lime juice which acidifies the blueberry jam, helping preserve it. Furthermore, the erythritol based low carb sweetener prevents the growth of bacteria. I often make double batches with the unopened jar sitting in the fridge for several weeks. I try to use the opened jar within 2-3 weeks. Make sure to start with a clean jar and always use clean utensils when removing jam from the jar.
Is Sugar Free Jam Keto Friendly?
Yes, sugar free jam is Keto friendly. While fruit contains natural sugars, lower carb choices like blueberries, raspberries, blackberries, and strawberries are perfect for low carb keto jams. Fruit is generally consumed sparingly and since jam is a condiment, only one tablespoon is used at a time. Most homemade sugar-free jams contain 1g carb per serving.
