This is a ginger root. You can buy it in the produce section of the grocery store. I found mine hidden on an end cap near the zucchini and green beans.
Peel and chop the ginger into chunks.
In a saucepan, add chopped ginger, 1 cup water, and 1 to 1 1/4 cups cane sugar depending on how sweet you want the soda to be. Cook on medium heat 5-10 minutes until sugar is melted. Turn off the heat and let sit for 30 minutes.
Strain out the ginger pieces and throw them away. Pour your ginger syrup into a jar and store in the refrigerator. We use a glass canning jar with a white plastic lid.
To make a glass of ginger ale, pour 3 Tablespoons of the syrup into a cup. Fill with club soda or carbonated water. (We use our SodaStream home soda machine to make the carbonated water.) You can also squeeze about 1/4 of a lime into the glass for added flavor.
