Make the rhubarb simple syrup by adding the sugar, water and chopped rhubarb into a medium-sized pot. Bring to a boil over medium-high heat. Then lower heat down to simmer for 15 minutes, stirring occasionally.
Set a strainer over a bowl and pour the mixture through the fine mesh strainer so most of the liquid is in the bowl. *Note: save the rhubarb solids that are strained out as it tastes just like a jam and is delicious on yogurt, oats or toast**
