What You Need to Know
Repeated freezing disrupts cellular structures via ice crystal formation, releasing bound water and concentrating functional proteins like albumin or gelatin through fractional thawing. Subsequent whipping incorporates air into this clarified matrix stabilized by interfacial protein films.
Creates ethereal foams without particulate interference, ideal for highlighting delicate flavors in sauces, cocktails, or garnishes.
