Put Fresh Strawberry (500 gram) into a big microwave safe bowl. Add in Granulated Sugar (1 1/2 cup) and Lemon (1/3 cup). Stir them around. Put the uncovered bowl into the microwave for four minutes on high setting.
Take the bowl out and give it a stir. Put it back for another fifteen minutes. In the meanwhile put a small plate into the freezer to chill. You are going to use that to test if the jam is ready to go into the bottle.
Take out the bowl carefully and give it a good stir. Put a small amount on the chilled plate, and put it back into the thre freezer for two to three minutes.
Run your finger through the sample on the plate. If the jam is still too runny, cook for a few more minutes, then test again.
Spoon the jam into a sterilized jar. Put a lid on, allow it to cool, then serve or put it in the fridge.
