Vanilla-Caramel Soda

Directions

1. 1
   Heat sugar in a small saucepan over medium heat. After about 5 minutes, when the sugar begins to caramelize and turn to liquid, tilt the pan from side to side to gently move the caramel around.
2. 2
   When the sugar has entirely transformed from white granules into amber liquid, add the water. The caramel will solidify upon contact with the water, but continue to cook for about 10 minutes more until the caramel has dissolved completely into the water.
3. 3
   Remove from heat and stir in vanilla and salt. Allow to cool to room temperature. (You will have about 1/2 cup of syrup, which can be covered and stored in the refrigerator.)
4. 4
   Into a glass of ice, pour 1 cup of seltzer and 1-2 tablespoons of syrup, according to taste. Stir and enjoy.
