Unripe mulberries apparently are the ticket according to what I read - so while syrup might not a an option, trippy jam may be! Apparently the tea from unripe red and white mulberries is very popular in Japan.
This probably explains why they cut down the mulberry tree at my old elementary school. Some do-gooder probably thought we were getting high, but I swear we only ever pelted people with the ripe ones and stained their clothes...
