Boston's rum tradition is nearly as old as Boston itself. Without the city's thirst for the sugar-distilled spirit, there'd have been no Great Molasses Flood. A recent addition to this tradition is the Daiquiri Time Out. Part drink, part ritual, it involves putting life's curveballs on hold by first having a well-made daiquiri. Usually just called a DTO, it's described by its creator, Andrew Deitz, as "a modern day drinking ritual that celebrates that act of taking a moment."
The way Deitz tells it (though there are other stories told as to its origin), the DTO was conceived when he and some friends on Martha's Vineyard were discussing another's actions after an unfortunate situation and decided he'd have handled himself better had he had a daiquiri first. The ritual spread to Boston bartenders, and the DTO now appears on many menus throughout town. Here is Eater's list of DTOs you can find around Boston. The DTO is meant to be spontaneous, so many of the listed drinks may not be available, but any of these bars would be happy to mix up a variant on the fly the next time you need a time out.
