Many years ago, a particularly cunning Southern Living writer convinced our editor-in-chief that “somebody” needed to fly out to Texas and search the whole state for the perfect margarita. She had all manner of scientific criteria, from the choice of tequila to the texture of the ice—none of which could be evaluated without a taste test, of course . . . for the good of our readers. Brilliant. Absolutely brilliant. We think our Frozen Margarita would’ve pleased her discerning palate—and yours.The perfect blend of salt, sweetness, slush, and spirits, it makes 8 cups of blissfully cold deliciousness, so it’s ideal for summer parties. You might think the recommended 8 cups of ice sounds like a lot, but you need that much with the limeade concentrate. Serve our Frozen Margarita with guacamole and chips or even pour it into popsicle molds. If any of your guests are from Texas, tell them you had the margaritas shipped in from San Antonio.
