Perhaps spurred on by the pandemic, there has been a proliferation of pre-mixed cocktails lately: often canned, sometimes classic but mostly too fruity and carbonated. Sometimes something has outstanding quality. To that short list, add Hercules Mulligan Rum & Rye, an uncommon blend of three Caribbean plums and three American ryes infused with ginger and a hint of bitterness to enjoy over ice or cut with soda. They call it an Irish classic; Garnish with a slice of fresh ginger. It sold out quickly when it was introduced in 2019 in limited quantities on Flaviar, an online spirits club, and it’s currently on sale at New York liquor stores. It was inspired by a recipe from the days of the Revolutionary War and is named for an 18th-century Irish seamstress who emigrated to New York and also followed the British. He was friends with Alexander Hamilton and is buried near him in the Trinity Church cemetery in Lower Manhattan. The scent of toffee and ginger wafts from the glass; The strong onslaught of amber whiskey is tempered with a pleasant syrupy finish.
