Moonshine using Everclear and Elderberry Concentrate

I make my own Lemoncello (or limoncello), and it is delicious. My apple pie moonshine is only so-so. Probably a matter of taste.

Now, I would like to make Elderberry Moonshine and have 8 ounces of elderberry concentrate. I'll purchase the Everclear (151 proof) when I have a recipe or two.

So that's the situation! Now, does anyone have a recipe that they will share? Thanks in advance.
