This sherbet is like summer in a bowl: light, refreshing, sweet and perfumed with the quintessential summer herb (which has a surprising affinity for cherries). It’s also ridiculously simple to make. It can get icy when frozen too hard, so eat it fresh from the ice cream maker or leave it on the counter to soften a bit if pulling it from the freezer. And here’s a little food trivia for you: Did you know that sherbet goes back to the Middle Eastern fruit-juice-and-water drink charbet? It has evolved into a dessert that’s lighter than ice cream — though in this case, low-fat buttermilk lends it a rich, tangy note.
