A fresh and crisp drink. I first made this to serve at an Asian-themed dinner party, and it was great! The original recipe called for crystallized ginger to be placed in the glass, but I felt weird about that so I left it out. I'm not sure what lychee puree is exactly, so I found canned lychees in syrup at my grocery store and blended them for a few minutes. I had to strain it a little through a colander because the lychees didn't blend perfectly so it was a little gross looking, but in the end I came out with a milky liquid that worked well.
