|300 g||sugar (white or brown)|
|juice of one lemon|
|piece of a cinnamon stick|
|pinch of salt|
Open the watermelon, cut it into pieces and remove the red flesh (for later consumption) leaving a small border, which will still give some reddish color to the dessert. Remove the green peel completely, without taking any of the white flesh. Cut it into small pieces and cook in the water for 30 minutes over medium heat.
After this time, add the other ingredients and cook uncovered, over low heat, for another 20 minutes.
