Sparkling wine is my aperitif of choice. It’s light and refreshing, it pairs well with just about any starter, and those bubbles always put me in a good mood. Occasionally, I will spring for a glass of French champagne, but I find Italian prosecco, Spanish cava or an American sparkling wine does the trick just as well for, typically, a much lower price, making it possible to enjoy that effervescence in an everyday way. It turns out sparkling wine also makes for a wonderful end to a meal, as a star ingredient in this easy, elegant, four-ingredient dessert.
