The Captain Ron is a complex combination of Haitian rum and rye whiskey from bartender Bryan Crowder of the Ice Plant Bar in St. Augustine, Florida. In addition to its two base spirits, the cocktail also features fresh lemon juice, falernum and grenadine. Falernum is a low-proof Caribbean liqueur and a staple in tropical drinks. It lends flavors of lime, ginger, almonds and spice, and it provides a unique way to achieve sweetness in cocktails without reaching for simple syrup. Grenadine is employed in much the same way, though it's worth considering your options before picking up a bottle from the store. Most commercial grenadines are bright red, cloyingly sweet and filled with artificial ingredients. Instead of resorting to a subpar grenadine, you can invest a few minutes of your time into producing a homemade version made with pomegranate juice, pomegranate molasses and sugar. It's worth the effort, as DIY grenadine lends a tart richness to drinks that can't be duplicated by anything you'll find pre-bottled. Put everything together, and you get a cocktail that is spirited but refreshing, with notes of citrus, spice and tart grenadine complementing the rich, oaky rum and bold rye. 11 Rum Cocktails to Try Right Now
