• 1 lemon
• 1 lime
• 1/4 cup sugar
• 1/4 cup water
• 1 8.5 FL oz bottle of seltzer (ingredients should only say carbonated water, nothing else)

Add sugar and water in a small pan. Stir constantly with a metal spoon over medium high heat for about 1 minute until the sugar is completely dissolved. Stop stirring and let the mixture come to a boil. Reduce heat to medium-low to low and simmer for 10 minutes. 

While the syrup simmers, cut the lemon and lime in half and juice them using a hand or electric juicer. (Squeezing also works but produces less juice.) Pour the lemon and lime in a glass. Next pour the chilled seltzer into the class and spoon off the foam that will form from the carbonation. Once the syrup is ready, remove from the burner and let sit for a few minutes to cool. (syrup can also be prepared ahead of time and chilled in the refrigerator.) Pour sugar syrup into the glass and stir. Makes one serving.
