Vietnamese Egg Coffee (Ca Phe Trung)

Vietnamese egg coffee — a Hanoi specialty of robust robusta espresso topped with whipped egg yolk and condensed milk — went international in 2025 after years as a traveler's secret. Invented at Cafe Giang in Hanoi in 1946 during a milk shortage, the drink combines the richness of dessert with the intensity of strong coffee. Specialty cafes in London, New York, and Sydney now offer variations.
