1 cup herbal tea of choice, brewed according to package instructions
1 cup of sugar
For the Tea Soda:
.5 to 1 oz tea syrup, to taste
1 cup chilled carbonated water
INSTRUCTIONS
For the Tea Syrup:
Stir to combine while the tea is still hot, then store in the fridge. Use within two weeks.
Note: the best way to make any syrup is by weight, so if you have a kitchen scale, use it to measure equal parts tea and sugar by weight, not volume. For the Tea Soda:
Pour the syrup into a chilled glass, and top carefully with the chilled carbonated water. No need to stir -- the syrup should self-mix as you pour the seltzer in, and stirring will reduce the carbonation.
