Caffè Shakerato (Shaken Espresso) vs Nam Manao (Thai Limeade)

Both drinks lean on ice and sugar, yet they put them to very different work. In the Caffè Shakerato, hot espresso dissolves the sugar before a vigorous shake with ice chills it and whips up a thick, creamy froth; the ice is then strained out, leaving a lightly sweetened, velvety, foam-topped coffee. Nam Manao is stirred, not shaken: lime juice meets a quick sugar syrup and cold still or soda water, then sits over a glassful of ice for a bright, sweet-tart, thirst-quenching sip.
