Like many others, I like a good cocktail every now and then, and I've always been impressed when my cocktail enthusiast friends would come up with a new drink or even just remember how to concoct a Clover Club (FYI, it's made with gin, raspberry syrup, lemon, and egg white). There's a secret bartenders and craft cocktail aficionados know, though: It's all about math, the simplest and most intoxicating math. Pythagoras would be so proud.
