I'm partial to honey as the sweetener with peaches, nectarines, mangoes, passion fruit and blueberries myself, but I believe most any fruit will do. I've seen it made with everything from pineapple to star fruit (carambola). Oh, and triple sec as the alcohol and a sprig of mint as a garnish.
It seems to be a drink of the imagination in which there is no absolute set of ingredients beyond the fermenting of fruit in wine, only suggestions. And by the beginning of your second round, you'll have lots of new ideas...
