Zabaglione (or sabayon) is a light, airy custard made from egg yolks, sugar, and a sweet wine (typically Marsala). It's whisked vigorously over heat until it thickens into a luscious, frothy sauce. Think of it like a boozy, grown-up version of egg custard. It is served warm and often accompanies fresh fruit, berries, or biscotti. Zabaglione offers a delicate sweetness and a subtle alcoholic kick. It is considered a classic Italian dessert.
