I post a different rum cocktail recipe before each Pirate Borg game and at least some of the players make them at home. (I avoid the crazy fancy tiki cocktails most people won't be able to replicate without a lot of advance warning and significant cash outlay.)
We've gotten enough recommendations for them anyway; let's see how they rank alongside more traditional gamer snacks. I tend to drink bourbon cocktails (especially Old Fashioned) in the winter, and gin cocktails (love me a G&T) in the summer.
