Combine water, sugar, and chopped pears in a medium saucepan over medium-high heat and bring to a boil.
Once boiling, lower heat and let simmer for about 15 minutes, until mixture has thickened and pears have softened.
Strain the mixture into a bowl, leaving behind the pears (push down on pears with a wooden spoon or spatula to extract as much juice as possible).
Keep syrup in bowl or pour into a mason jar and place in fridge to cool completely before using.
