Cold foam works because milk proteins trap air bubbles when agitated, creating a stable foam without any heat. Strawberries contain aromatic ester compounds that give them their signature berry scent — those same compounds carry beautifully through dairy fat, which is why strawberries and cream is a pairing that spans almost every cuisine.
