Very much a tiki style cocktail, minus the flowery garnish and giant mug filled with crushed ice. The spices are the key element here, both with the bitters and the falernum. You could easily double this recipe and serve it over crushed ice with a sprig of mint and a hibiscus flower for color and a straw and it will work just as well. Hell, make a punch out of it by multiplying everything by 16 (whole bottle of rum, 4 ounces of lime, simple and falernum, and a tablespoon of bitters). It’s all good.
