About once a month, I take the women who work for me out to test cocktail recipes (jealous?). On a recent outing to a hotel bar in midtown Manhattan (it’s swanky, I swear!), the bartender introduced us to The Airmail: Sweetened with honey, woozy with rum and sparkling from a champagne topper. Make it and be inspired to send your lover a lusty letter instead of shooting him a text. Your sex life will thank me.
