Step 1

Set aside sugar and vanilla, and combine all other ingredients together in a saucepan. Simmer together for 30 minutes.

Step 2

Stir in the vanilla and sugar until dissolved. Simmer again for another 30 minutes until the mixture is thicker and has the consistency of syrup.

Step 3

Strain out the mixture into a jar or container, then let cool.

Step 4

Pour 1/2 cup of chilled seltzer water into a glass, then mix in 1/2 cup of chilled syrup. Make sure both are chilled for the most fizz possible.

Step 5

Sip and enjoy!
