Now what would you call this thing? Huckleberry Ginger Fizz?
The first name that comes to mind is a "Huckleberry Finn"
A quick search turned up a few Huck Finn cocktails (all different) but none with the full Huckleberry moniker. This one sounds closest to the flavor profile of your drink. I think I'd pick lime over lemon if you want to tart it up, but that's just me.
Either version sounds very refreshing
