New fave cocktail

For years, I've been a beer- and wine-drinker only. Lately, though, I've noticed the craft cocktail bandwagon circling around, and I'm ready to jump aboard. On Friday, a friend had some sort of gin/basil thingy at one of our moderately-hip places, and I was able to recreate it this evening:

Basil-Gin Smash (It really needs a hipster name- like Gin Basilico)

Muddle a handful of fresh basil leaves and 1/2 lemon in a cocktail shaker (it's more effective if you squeeze the lemon juice onto the basil leaves and then muddle and then add the lemon quarters and muddle again);
Add ice; 1 oz simple syrup; and 1 1/2 oz gin to shaker;
Shake vigorously until your hand is like to freeze off (c 30 sec);
Pour over rocks glasses filled with ice;
Garnish with basil leaf.

So, I made some simple syrup this afternoon. That and fresh fruit juices, I think, are key to the awesome cocktail (also true of my craft margarita, which uses fresh lime juice instead of Rose's.
