Dark and Stormy
In a small pot over medium heat, combine the sugar, water and the ginger. Bring to a boil then shut off the heat and let cool to room temperature.
Fill 4 glasses with ice. Pour seltzer water into the bottom third of each glass. Add 1/4 cup of the ginger simple syrup to each glass and gently stir. Put a teaspoon upside down over the glass and pour 1 shot of rum over the spoon, so that the rum stays separated from the seltzer.
