After seeing the recent espresso post, I figured I'd start a thread for cocktails. I've been recently getting into decent rums (Smith & Cross is a favorite) and have been playing around with different recipes and uses.

So far, I've found a good spring/summer spritzer of cachaça (raw sugarcane distillate from Brazil, with a grassy, vegetal flavor), elderflower liqueur, and tonic water. I need to refine it, but I think I'm at a 2/0.5/4 ratio of spirit/liqueur/tonic. I love the way the herbal-sweet elderflower mixes with the cachaça, balanced by the bitterness of the tonic.
