What You Need to Know
Lecithin in egg yolks stabilizes air bubbles while heat coagulates proteins, creating a foam with 3–4x volume increase. Sugar acts as a plasticizer, delaying protein denaturation.
Forms the base for desserts (zabaglione) or savory sauces (hollandaise variations), balancing richness with lightness.
