In New York Time Cooking's cookbook, Cookies: The Best Recipes for the Perfect Anytime Treat, recipe curator Vaughn Vreeland presents a cookie for every occasion and need. And for a barbecue or a beach trip, he recommends these salted Margarita bars. "Key lime pie’s boozier, saltier cousin, this edible cocktail is an ideal party dessert, mingling all the fun of a margarita—and its salted rim—with the efficiency of a slab pie," he writes. For the bars, he recommends using a blanco tequila for "its milder taste."
