Apple and blackberry cordial

1kg apples (windfalls are fine, just cut off the manky bits before weighing)
1 kg blackberries
700ml water
sugar
Chop the apples -
Strain using a jelly bag overnight.
Measure the resulting juice and add 700g of sugar to each litre of juice.
Bring to the boil just, stirring the sugar to dissolve ( you don't want to cook this a long time or the pectin present might result in jelly rather than cordial!)
Bottle in sterilised bottles. Keep in the fridge and drink within a couple of weeks, or freeze.
