Wilfred Sands came up with this drink, the signature cocktail of the exclusive and stunning Lyford Cay Club, when asked for a rum drink that was not overly sweet and could be served in a short glass. Forty-two years later, Sands still serves up Rum Dums from the men’s locker room at the Lyford Cay golf course. The recipe has been kept concealed, but Avenue magazine made it a mission to uncover the original Lyford Cay Club cocktail with the following recipe. 1 1/2 ounces light rum 3 1/2 ounces sweet and sour mix (recipe below) 1 ounce dark rum (Sands uses Meyer’s Jamaican Rum) Sweet and Sour Mix: 1 cup lemon juice 1 cup simple syrup (boil equal part sugar and water, stirring until sugar is dissolved) 2 cups water 1 raw egg white. Stir all sweet and sour mix ingredients together in a pitcher. Combine light rum and sweet and sour mix in a blender, and briefly blend to mix. Pour over ice in a short chilled glass. Carefully float the dark rum over the surface of the drink so it forms a separate layer. Serve immediately. We think a Rum Dum is best served in the environs of the Lyford Cay Club but we realize that one can’t always be cloistered behind the pink gates. Option B is to put on some Astrud Gilberto, find a girl swathed in a Jules Reid number and wait for night to fall.
