Simple No-Cook Blackberry Jam with Ground Flax Seeds

I have always had a thing for mashing up blackberries and spreading them on bread. It’s the definition of summer luxury. When they’re ripe, there’s nothing better than the sweet and intense burst of flavor that you get from blackberries.

I don’t make a lot of jam at home, mostly because I am always so overwhelmed by the amounts of sugar poured in. So while I do like the occasional jar of homemade jam in the winter when I am missing the tastes of summer, it’s not more than an occasional treat. However, in the height of summer, I do like to make this small batch version of jam, that doesn’t require any sugar at all.

In fact, to make this jam, you don’t even need to cook your fruit. All you need is ground flax seeds, which work as a thickener, making for a jam that’s easily spreadable and tastes 100% of fruit. I know that everyone is on the chia seed jam bandwagon, but I prefer the texture that you get with ground flax seeds, and chances are that flax seeds are grown somewhere far closer to you than chia seeds are.

Note that as this jam is made without sugar or cooking, it isn’t made to preserve. So if you want it to last longer, store it in the freezer and take it out when you’re ready to use. It will keep for a few days, which is why it’s nice to just make in small batches which you can consume quickly.

You can use this method to make small batches of fresh jam from any variety of summer berries. Raspberries and blackberries perhaps?

Quick Blackberry Jam with Ground Flaxseeds


1 cup (4.5 ounces, 130 grams) fresh blackberries

Juice of 1/2 a small lemon

1 tablespoon ground flax seeds

In a bowl, mash the blackberries with a fork or spatula. Add in the lemon juice and ground flax seeds and mix together until well blended.

Pour into a glass jar and let sit to thicken for at least 15 minutes before using. If you want the jam to be a little thicker once it has set, you can add in more ground flax seeds.

Store in the refrigerator.

    I just made this with mixed frozen berries defrosted and mashed and it was delicious (I added some sweetener though cos I’m a sweet tooth!) I’ll definitely make it again and can see it becoming a staple. I can see what you mean about the flax being a bit more “local”, plus there’s also an issue I have with oxalates (I’m prone to kidney stones) and flax is very low in them whilst the chia seeds are very high apparently. Thanks for sharing!
