Is The Southside The Mojito's Gin Based Cousin?

The Southside, is a hidden gem of a drink and underrated in my opinion. The Classical parings of Mint and Citrus, with complexity of a Gin works well. I think I've spammed this point enough already, but if your fan of Mojitos and Gin give this a try!
Ingredients
