Ok, I'm back with results. I doubt many here even drink green tea so I
might just be talking to myself.
Made the tea and the blueberry broth yesterday then refrigerated them
separately to chill overnight. The tea was good as always but the
blueberry "broth" was weak. Needed twice as many blueberries or just
reduced.
Anyway, I just mixed them half and half. Not enough blueberry taste but
still better than plain green tea.
I will definitely make this again. Next time, I'll just make a
concentrated blueberry syrup to add to the tea.
It's a tasty and healthy cold drink. Just 3 ingredients too - water,
green tea, blueberries.
