Frozen Cucumber Margaritas with Chili-Sumac Salt
August is the laziest month, in the best possible way. It seems to move a little slower than the other months of the year—in theory because of the heat, in fact because so many people are on vacation. It’s sluggish, languid even, but always welcoming. (After all, it’s far more fun to be lazy with friends.) All of that makes August, in my mind, the best month for leisurely dinners outside, for grilling in the backyard or by the beach or the lake, for cooking unfussy food. This means, of course, that it’s also prime frozen cocktail season.My most recent slushy obsession is a tequila, cucumber, and coconut water creation, blended up with cilantro and lime and rimmed with a mix of chili powder, sumac, and salt. It’s an ode to my favorite Mexican street snack: fruta con chile y limón, little bags of sliced mango, cucumber, and jicama usually sprinkled with Tajín, a spicy and sour snack seasoning. I make the icy concoction in big batches, and it never lasts very long, but a little advance prep and direction empowers my guests to blend more themselves without disturbing my valuable chill time. I peel and chop several cucumbers in advance, portion them out, and freeze them before guests arrive; squeeze lots of lime into a bowl; and chop an extra-big bunch of herbs on the side. The chili-salt mixture sits on a plate on the counter for people to sprinkle and rim as they please. And any extra doubles as seasoning for crunchy veggies, grilled corn on the cob, or a platter of watermelon. It’s August at its best.
