The Rum Swizzle is the national drink of Bermuda. It's enjoyed in bars across the island nation and has become a staple on Tiki bar menus across the world. Swizzles have taken different forms over the centuries, with references to the drink dating back to the 18th century, but the Swizzle Inn, which houses Bermuda's oldest pub, is associated with the modern version of the cocktail. Rum Swizzle recipes vary, but most have three ingredients in common: rum, fruit juice and a sweetener like grenadine or falernum. It's common for swizzles to contain multiple rums and juices, adding flavor and complexity to the drink. That convention is what you'll find in the Bermuda Rum Swizzle; it calls for two different expressions of Gosling's rum, a locally made brand that's a popular choice in cocktails and a must-have when making the Dark 'n Stormy. To prepare a Rum Swizzle, it's traditional to use an authentic swizzle stick. Real swizzle sticks are long stems snapped off a tree native to the Caribbean, and feature multiple prongs that protrude horizontally. When spun rapidly between your hands inside a cold cocktail, the stick will create a thick layer of frost on the outside of a glass—the sign of a perfect swizzle. This recipe is made in a pitcher and serves four people, but you can easily scale the ingredients up or down to accommodate more or fewer servings. If you're making one cocktail, simply cut the proportions into quarters, shake everything with ice, and strain the contents into a rocks glass over fresh ice. While it's always fun to drink with friends, companions are not required to enjoy the Bermuda Rum Swizzle. 5 Essential Rum Bottles Your Home Bar Needs
