Sabayon is a foamy dessert that typically has to be made just moments before serving—if left to stand for too long, it deflates. With the help of a siphon, you can make the sabayon hours in advance, and it will still be perfectly airy when it’s time for dessert. Slideshow: Fast and Easy Desserts
How to Make It
Bring a medium saucepan of water to a simmer; turn the heat to moderately low. In a large heatproof bowl, beat the egg yolks with the sugar. Set the bowl over the simmering water and whisk the yolk mixture until it’s hot and foamy, about 4 minutes. Gradually add the Marsala and cook, whisking constantly, until the sabayon is thickened and leaves a ribbon trail when the whisk is lifted, about 4 minutes longer. Don’t cook the sabayon for too long or it will curdle.
Remove the sabayon from the heat and let the sabayon cool slightly. Pour the sabayon into the canister of a 1-pint iSi Gourmet Whip Plus siphon (see Note). Seal the siphon and charge it with one iSi cream (N20) cartridge according to the manufacturer's instructions. Shake the siphon to distribute the gas. Repeat with an additional cream charger. Refrigerate until ready to serve, if desired.
To serve, hold the siphon upside down and shake it. Press the lever to release the sabayon.
