Blackberry and apple jam is probably the favorite jam in this household, I'm in trouble if a batch doesn't get made every year. Not that it's a chore, as picking blackberries is a totally pleasurable way to pass the time, and making the glossy deep coloured jam one of the best things to do with the fruit.
We planted several blackberry canes in our boundary hedge, at the same time as the hedging plants. They are a thornless variety, which is a great idea, although not so if you plant them in a predominantly hawthorn hedge. I try and use about half of this variety and half from the local hedgerows, the difference in size, flavour and texture between even just the canes round our local lanes is quite noticeable. Rather than go down the single variety route I feel this is one case where a blend of berries works well, adding interest to the finished jam. Anyway, I could never get enough of one variety to make it worth while.
The best place locally to pick blackberries in round the edge of the village cricket pitch, the same place that provides elderflowers, the apples came from my in laws back garden.
I use a trusted recipe from the "Good Housekeeping" Cookery Book

Recipe Costs
£5.89 1.8kg blackberries (this is a PYO cost, tesco would set you back £23.89, mine were free)
£0.94 700g cooking apples, peeled, cored and sliced (equivalent cost, mine were free)
£2.51 2.7kg sugar
£0.20 knob of butter
£9.54 Total (£2.71 without buying the fruit)
£2.12 per kg jam (25% of the cost of similar jam at ocado), £0.60 without buying the fruit (7% of the cost of similar jam at ocado)
Peeled and chopped Bramley apples.

Adding sugar to the mashed apples partially cooked blackberries, the white and rich purple is an amazing contrast of colours.

After adding sugar before boiling for ten minutes, a knob of butter is added at this stage which makes the jam more glossy in appearance.

After boiling for ten minutes the apple has broken down and the jam thickened.

Potting in steralised jars with greaseproof paper discs to stop any mould developing. I usually steralise the jars by washing them well, then without touching the insides heating them to about 100 degrees centigrade in the oven, I let them cool a bit before adding the jam. I soak the lids in boiling water for 10 minutes and then shake them dry, again without touching the insides.

The finished jam is a delicious colour and thankfully ready to eat straight away, best on toast at any time of the day.

Taste Test
Can't beat it really, tastes great. We have a variety of small hard blackberries in the hedges near us that survive the cooking and add a bit of texture.
