Vermouth adds an herbaceous finish to this Sabayon recipe—which is an airy, mousse-like dessert.
Put egg yolks, sugar, a pinch of salt, and vermouth in a medium heatproof bowl set over (not in) a pot of simmering water. Whisk constantly until pale and fluffy and quadrupled in volume, about 10 minutes. Serve warm, with fresh fruit, such as raspberries.
