💭 What is chia jam?
Chia seed jam comprises chia seeds and a fruit of your choice. The fruit is heated until it releases its juices and breaks down into a syrupy liquid. Then you add the chia seeds, give it a good stir and set aside for around ten minutes. The chia seeds absorb the fruit juices and expand, giving you a lovely thick jam.
I always think of chia seed jam as the 'easy' jam to make. It doesn't require thermometers, lots of time or a ton of steps, and you can whip up a batch in less than half an hour to spread on your toast or rice cakes. This blackberry chia seed jam can also be made without adding any extra sugar (maple syrup is optional for this recipe).
🥣 Ingredients
This is a four ingredient jam, although if you prefer to do all blackberries it becomes a three ingredient recipe! You will need:
- Blackberries: pick your own if they are in season, or get from the store. Make sure they are nice and plump for extra juiciness. And if you pick your own, then definitely wash well and check for bugs . . .
- Blueberries: these are optional. You can either do all blackberries or a mix with blueberries.
- Chia seeds: these little seeds absorb the fruit juices and swell up to become gelatinous in consistency and so form the chia seed jam. I like the Terrasoul organic chia seeds.
- Maple syrup: for a touch of extra sweetness.
📖 Variations on the recipe
You can have all blackberries for this jam, or combine with blueberries too.
The maple syrup is optional, but will add some sweetness to the jam. But simply leave out if you prefer.
If you don't follow a low histamine diet, then you may like to add a little lemon juice to the jam as well.
🔪 Step by step instructions
This blackberry chia jam is very simple to make, and requires just a few steps.
Steps 1-2
Add the fruit and maple syrup to a pan and heat on low (I have it on as low as it can be) for 5-6 minutes so the fruit breaks down and becomes syrupy. You can press it against the side of the pan with a spoon to help it along.
Step 3
Turn the heat off and add the chia seeds.
Step 4
Stir very thoroughly so the chia seeds are all combined with the fruit mixture. Set aside for at least ten minutes so the chia seeds have time to absorb the fruit juices and swell in size to form your jam.
💭 Recipe tips and notes
- Cook down the fruit so that it has at least half dissolved into a liquid.
- You can use all blackberries or a mix of blackberries and blueberries if you like!
- If you like a very thick jam, then you can use 2 tablespoon of chia seeds.
- The jam won't be ready right away, you need to let it set for at least 10 minutes to thicken. Then enjoy!
📋 Frequently asked questions

Hilary says
How long does the jam last for and how do you store eg in air tight jars or in the freezer to keep for later etc? thanks.
Claire says
Hi Hilary, you can keep the jam for a couple of days in an air tight container in the fridge, but if you're a low histamine reader then food storage isn't usually recommended due to histamine formation. And yes, you can freeze for a short period of time, 2-3 months, although I haven't tried it myself. Canning is not recommended.
