Mai Tai

This drink could go in a number of different directions, so you'll want to be a bit careful here — no need to be heavy-handed. For the dark rum, it could be spiced or not; the extra lime will balance out any of the spices anyway. If Orgeat is hard to find, substitute almond extract in a simple syrup, or, if you're really brave, an almond liqueur. But if that already pushes it to the edge, you'll want to pick your orange flavor carefully — at that point, go with maybe just triple sec. Orange Curaçao is fancier. However, there are some other really strong orange liqueurs that could push this drink into pure dangerous territory! Shake and strain over ice. A mint garnish works well; an extra lime looks good on top, but you run the risk of too much lime if the lucky recipient squeezes it in.
