Cabell Tomlinson, bar director at Frankies 570 Spuntino in New York City, grew up in the South, where, she says, "the summer air was scented with honeysuckle and lemon balm." Those childhood memories, along with a recipe for the classic Bee's Knees cocktail (rum, lime, and honey), inspired this thirst-quencher. It's equally good with lemon vodka (try Charbay Meyer Lemon Vodka) or white rum (we like Flor de Caña Extra Dry 4 Year). Lemon balm is available at many farmers' markets. Better yet, try planting pots of the prolific herb in your backyard.
