Warm the sugar in a large pyrex bowl for 2 minutes.
Add the Raspberries and stir very well.
Microwave until boiling point is reached * approx. 5 minutes.
Stir every other minute to ensure that all the sugar has dissolved and is not sticking to the bowl.
Microwave until setting point is reached approx. 3 minutes, test for setting (drop a little jam on a saucer, if after the skin wrinkles as you draw your finger over it, the jam is ready.)
Pour into sterilized 500g Jam jar seal and label.
