I promise this really is as easy to make as it sounds. And it's delicious. Even hubby who won't eat jam unless its on a scone covered with real clotted cream has been eating it.
All you need are equal quantites of fresh fruit and sugar.
So I used 400g raspberries
400g granulated sugar
2tsp lemon juice (its roughly 1tsp to each 250g fruit)
This made two jars.
Heat the jam jars. Either microwave or fill with boiling water.
Put everything in the pan and mash slightly.
Put a small plate into the freezer to chill.
Heat and bring to the boil
Boil for 5 mins.
Then put a tsp jam onto the cold plate and put in fridge for 30 secs to test setting point
If the jam wrinkles when you run your finger through it, its done.
other wise boil for another minute and retest.
decant into the hot jars and seal immediately.
