Slice up the ginger root into medallions.

In a pot bring the sugar, water and sliced ginger to a boil on medium heat. Once it begins to bubble, turn the heat down to low and simmer for 30 minutes.

Pour the syrup through a sieve to catch the ginger. You should have about 1 cup of syrup, if it is a bit less than a cup, add water until it is 1 cup so it isn’t too sweet and syrupy.

To make one drink add 2 Tbsp syrup to a glass and pour ½ cup of seltzer on top. Squeeze a little lime into it. If you want to make a larger quantity, mix all the syrup with the liter of seltzer and squeeze lime to taste in each drink.
