I sometimes add a dash of cinnamon to my bowl of kava, but because I prefer the nutty peppery tones of kava over the bitterness that comes with it. Cinnamon seems to do a good job of toning down the bitterness and letting the nutty undertones come out more, I like that. I don't worry too much about making kava itself taste better, as I prefer to have fresh cut fruit or some other light snack in a bowl to chew on after I've had a shell. Nothing enough to fill your stomach, but enough to soothe your tastebuds if it's a particularly bitter kava. For me it's just root and water, I enjoy the "WOW OH WOW" feeling of chugging bitter kava. Makes it feel more worthwhile, I don't know. I like it.
