If you want good sweetness but not extra tastes to distract the tea, use white crystal sugar, the next best is rock sugar, like those that we have in our grocery stores in HK, if you are familiar with this place. Grind the chunk a bit before trying to dissolve it. Or use low fire to dissolve it, but not over cook to brown. I have written a bit about it in the ice tea special feature.
