Ooh, good spot about the blackcurrant/blackberry mix up! In that case I will definitely use some apples to make sure it sets. Thanks for all the links and tips I am usually a chutney girl but am branching out...

I have also found this link which may prove useful for people who know what they are doing a bit more and don't need a set recipe:

Think the BBC may have got their blackcurrants and blackberries mixed up! Early blackberries have a medium amount of pectin at best and late ones are lacking. I always make Blackberry and Apple Jam - making sure I use cooking or crab apples which are rich in pectin.

Right... Ive consulted my Book by Val.
Blackberries are lacking in pectin and you would have problems getting a good set.
You should make blackberry and apple jam.  The apples are neutral and the taste will be the blackberries.


450g apples after peeling
1.4 kg blackberries
140ml water
1.8kg sugar


The only difference on method is to soften the apples in a simmer first and then add to the blackberries as to the method previously mentioned, before the sugar phase.

blackberries being low on pectin , you can use Jam Sugar which contain pectin

Bob i am sure early blackberries are high in pectin but later ones are lower. Google seems to say the same but i cant get to vals book right now. Never had a problem setting blackberry jam

Blackberries are low in pectin.
I use 3 lb blackberries
12 oz of grated Bramley apple.
3lb sugar 
Gives a good set but a strong taste of blackberries.
