There are a few recipes out there online that are really complicated, some of them involving yeast. This is my no-nonsense version. It is quick and easy, and tastes really special. I like to keep this syrup in a squeeze bottle in my fridge. I mix it with a carbonated mineral water such as Perrier. You could also use club soda, and if you are concerned about the sodium, look for low-sodium club soda.
2 inch piece of fresh ginger, sliced
2 cups boiling water
2 packets of Splenda
1. Place the Splenda and the ginger into a container that you can easily pour from, such as a measuring cup.
2. Cover with boiling water and let steep for a few hours, then strain into a container.
3. Pour a small amount of syrup into a glass with ice and top with carbonated water.
