Mixology is fun—when you have the wherewithal. But sometimes it's not an option, like on a plane, or after a long day at work. Drop one of these wondrous cubes into a shot of booze, wait a minute or two, muddle it—and drink up. Hand-infused with concentrated cocktail ingredients like spiced cherry and Angostura bitters, vermouth extract, and spearmint leaves, they make instant, delicious Manhattans, Old-Fashioneds, and Mojitos. Keep them on your bar cart, or in your travel kit: they'll sail past security without a hitch. A straight-up excellent gift for cocktail lovers, travelers, and frequent entertainers.
