Sabayon (called zabaglione in Italy) can be served over cake, ice cream, or fruit. Use this recipe when making our Oven-Roasted Apples with Cider Sabayon.
Fill a medium stockpot a quarter of the way full with water. Bring to a boil, then reduce heat and let simmer. Fill a large bowl with ice water; set aside. Combine sugar and egg yolks in bowl of an electric mixer fitted with a paddle attachment, and beat until mixture is pale and has a thick consistency, about 2 to 3 minutes. Scrape down sides of bowl with a rubber spatula one time while beating. Add cider and Calvados, and beat for 2 more minutes.
Transfer the yolk mixture to a large metal bowl, and set over simmering water. Whisk together for 6 to 8 minutes, until the sabayon thickens and is fluffy and slightly stiff. The sabayon should begin to look satiny and start sticking to the bowl slightly. The air bubbles will become very fine, instead of large and loose.
Set bowl in ice-water bath. Continue whisking sabayon until chilled, about 3 minutes. Whip the cream to medium-stiff peaks, and fold into chilled sabayon. The sabayon can be stored in refrigerator for up to 24 hours.
For best results, when setting sabayon over simmering water in step two, choose a bowl that just fits inside the pot.
