At the Swizzle Inn in Bermuda they only sell these by the pitcher. The idea is you’re going to sit all afternoon (yes, daytime drinking…the only respectable kind of drinking) and drink the stuff in bulk. “Swizzle Inn/Swagger Out” is their slogan, if that gives you a clue… Here’s a single serving recipe, which is a little different than the original, but is faithful to it, courtesy of the Reagans.
In a 11 or 12 oz hi-ball glass squeeze two wedges of lime and one lemon wedge 2 dashes of Angustora bitters
fill glass with ice (yeah, just plain old ice)
1 oz gold rum
1 oz of Gosling’s Black Seal rum
3/4 oz of Falernum (preferably Gosling’s)
1oz pineapple juice
1oz orange juice
splash grapefruit juice
drop a couple of cubes on top to combat that hated “settling” of the ice problem and…
Don’t make the drink in a shaker, shake it and then pour it over ice. Why not? Because it’s called a swizzle and therefore the drink should be made in the glass and “swizzled” with, yup you guessed it, a swizzle stick.
