Add the watermelon to your blender, then purée until smooth.
Place a fine mesh strainer over a bowl, then strain the puréed watermelon to remove the pulp.
Discard pulp, then measure one cup of strained watermelon juice (save extra juice for another use). Add the juice to a mason jar (or other container), along with the sugar.
Stir the watermelon-sugar mixture for a couple minutes. Then let the mixture sit until the sugar is totally dissolved, stirring every 5 to 10 minutes. It should take about 30 to 45 minutes total.
Refrigerate the Watermelon Syrup until ready to use. Enjoy!
