1/8 t baking soda
1/3 cup sugar
8 cups water
In a measuring cup or small pan, cover 6 tea bags with 2 cups of boiling water. Stir in 1/8 t baking soda (this keeps it from looking cloudy). Let it steep for about 15 minutes, then remove the tea bags.
Measure 1/3 cup sugar into a large pitcher. Add the steeped tea and whisk to dissolve the sugar. Add 6 cups cold water. Whisk to combine, cover, and chill.
