Shake, strain, Collins glass, crushed ice, garnish.
Recipe as presented in Imbibe. The bar's facebook page indicates this used Mt Gay Eclipse and E&J. A blogger suggested Flor De Cana 7 year. I've tried with Stiggins' Fancy Plantation Pineapple with excellent results.
The bar's facebook page also calls out "special" bitters, and black tea, and chai. Perhaps the latter two were removed when this was changed from a punch to a single serving? Pictures show wine glasses garnished with pineapple.
