Here in the Northern Hemisphere, we are rapidly approaching gin n’ tonic season. But don’t you just hate it when your gin dilutes or the drink becomes unacceptably warm before you have finished imbibing? Haven’t you always wished for a gin n’ tonic recipe that was optimized to maintain a temperature of 20°F and 0% dilution throughout the 20 minutes it takes to properly savor a drink? If you prefer your drink recipes include multiple graphs, there’s a post at Kaiser Penguin that will make you very, very happy. (Via Andrew Thaler)
