Before there was anything frozen, peach or rimmed in raw sugar, there was this. Christopher Idone’s classic margarita relies on real lime, a dignified splash of triple sec and a chilled cocktail shaker. I’d be proud to serve this to anyone, with only the fresh salsa and tomatillo guacamole below, or as a start to an taco- and pepper-laden feast. Practice this technique of rolling the rim of the glass in a dish filled with salt – the same technique applies to making a michelada, my other favorite summertime beverage.
