Blackberry Jam

Pick blackberries from higher branches to avoid dogs' and foxes "traces".

Mix ~ 800gr of  blackberries with 500gr of jamsugar in a heavy based pot and slowly bring to a boil whilst stirring.

Once it is at a rolling boil leave to boil for 3 minutes and do the drop test:

Drop a bit onto a cold saucer - if it sets, take jam off the heat and fill into 

sterilised jars. If still liquid, boil a bit longer.

Wash jars in hot soapy water, then put them upside down in a 150 C oven for 10 minutes before filling them.
