Egg yolks are whipped with sugar and a fragrant fortified wine to make this creamy foam. Black pepper cookies provide crisp textural contrast, and their spice cuts the dessert's richness.
Whisk yolks and sugar in a medium glass bowl until creamy, about 5 minutes.
Set bowl over a pan of barely simmering water. Add Marsala; whisk until mixture almost doubles in volume, about 15 minutes, scraping down sides of bowl as needed. Serve with pepper cookies.
