Tried mixing with sodium free club soda – in short it didn’t work. It fizzed like crazy, the tea didn’t dissolve well at all, and it tasted like salty seaweed water. What was I thinking? I dumped it out. Next time I’ll try making a strong cup in 5-6 oz water, then add a splash or two of club soda for a hint of sparkle. Maybe I’ll add a drop of agave if it needs sweetener to balance the club soda.
