Blackberries make absolutely scrumptious jam. They are low in pectin, which is why you need citrus (lime or lemon juice will do) and sugar with added pectin (jam sugar) to ensure it sets well.

I halved the recipe as I didn't have enough blackberries, added mulberries to bulk it out and only 1 lemon- it was gorgeous!! First time I've made jam and will certainly not be the last.
Had never made jam before. This was a simple recipe that produced a lovely thick set jam (also followed the how to make jam article.) Definitely will be out picking more blackberries and making another batch again soon.
I made 21 jars of this today and it's scrumptious! Yes, it does taste lemony but we like the slight tartness that it adds. I still think the blackberry flavour powers through though. Try adding half the amount of lemon, it will probably still set OK as long as you use the jam sugar, or add apple instead of the lemon. There seems to be such a glut of blackberries this year, it's worth experimenting, but this recipe gets 10/10 from me.
Did anyone else find this jam to taste overwhelmingly of lemon? I followed the recipe and added the zest and juice of 3 lemons and found that it has totally overshadowed any blackberry flavour.
