Scrape the skin from the ginger roots with a small paring knife or a spoon. Give the ginger a quick rinse under water.
Slice ginger into thin slices (about 1/3-inch thick) and smash or crush them.
Add ginger, sugar and water to a small saucepan over medium heat. Stir to dissolve the sugar. Once the mixture starts to boil, skim off foam and lower heat to a simmer.
Cover the saucepan with the lid slightly askew and simmer gently for 30-35 minutes to thicken the mixture into syrup.
Strain the syrup. Store the liquid in a clean jar or bottle with several slices of the ginger you just strained. Let it cool and then store in the refrigerator with the jar/bottle lid on.
