Lime Basil Gin & Tonic

It's the last Friday of summer.  Here's a cocktail inspired by a drink I had somewhere once, the lime basil growing abundantly in the backyard, and LIME FLAVORED EVERYTHING in Mom's fridge.

A squeeze of agave
2 ounces Limeade
3 ounces Lime gin
2 ounces Lime perrier or tonic water
11 Lime Basil leaves (mine are on the small side, so if yours are larger, adust accordingly)
(in the absence of LIME FLAVORED EVERYTHING, plain gin, perrier/tonic, and/or basil will do just fine.)

Honesty:  Those measurements are complete estimates of what I did based off of the interwebs.  I believe you are a smart, capable adult who deserves this cocktail and can guesstimate your measurements just as well as I. ;) 

Place 10 basil leaves in your hand, clap.  Pummel them in a small glass with agave and a small amount of your limeade. Strain out basil leaves.  Add to tumbler with gin, perrier and the rest of the limeade, stir well.  Garnish with final basil leaf.
