Cut watermelon in half. Cut in quarters and cut of the flesh by running a knife underneath the skin.Chop them into small cubes.

Take sugar and lemon juice in a blender and blend it to a puree. Add the watermelon cubes and blend it so that it becomes a liquid.

Pour this into a wide freezer container and freeze it for 5-6 hours. I left it there over night.

Now take a spoon or fork and scrape the granite so that it gets so what loose.

Put the lid back and put it in the freezer again and leave for 2 hours.

Now take it out. It will be hard now. Use a spoon or fork and scrape it of starting from a end. Scrape all over the container.

Now put it in the freezer till serving. You can take some granita in a bowl and decorate it as per you wish.
