I’ve mentioned more than a few [thousand] times during my cooking show that you can make your own simple syrup at home. It takes around five minutes and tastes better than the stuff at the store. Plus, you can flavor it with whatever you like, such as ginger. Or mint. Or nothing!
If you like a strong ginger bite, boil the ginger with the simple sugar for a few minutes. If you prefer your ginger syrup with all bark and no bite, add the ginger when you take the syrup off the heat and let it steep until it comes to room temperature.
250 g (~1 cup) granulated sugar 250 g (~1 cup) water 125 g (about 1/2 cup) ginger, peeled and sliced 1/16″ thick
Add sugar, water, and ginger to 1.5 qt saucepan over high heat. Bring to a boil, stir to dissolve the sugar, then cover and let cool to room temperature. Strain out the ginger—reserve for another use!—and transfer the syrup to a glass jar or plastic squeeze bottle. Refrigerate.
