Playing around with my signature cocktail, the Shaddock, resulted in this Sour Flower Power Shaddock.

I wanted to taste what happened with fresh citrus plus a few drops of acid phosphate. To soar above that sour punch, I used Geranium Gin for its strong geranium distillate.
Et voila! The Sour Flower Power twist on a shaddock.
