What You Need to Know
The mechanical action of whisking introduces air bubbles while gentle heat (60-65°C) partially denatures egg yolk proteins (livetins, phosvitins) to stabilize the foam. Ethanol from Marsala wine lowers interfacial tension between phases.
Serves as both a dessert sauce and standalone preparation, with the alcohol content providing flavor complexity while acting as a microbial inhibitor.
