can anyone speak to the flavor of Rubus leucodermis?
Those of you in the PNW may be aware of this native species.
According to Mentalfloss and a few other internet sources, this is the source of the flavor known as "blue raspberry". Produced synthetically nowadays, of course. There used to be a foodie-type blog with a longer story of its purported discovery: something like a flavor chemist who was out in the woods and tasted some, and thought "gee whiz, we better figure out what makes these tick". But I can no longer find that link. Do they really taste like blue raspberry slurpees, popsicles, etc?
