This jiggly, wiggly custard of silky, sweet deliciousness was adopted by the Vietnamese during the French colonization of Vietnam in the 19th century and is a common dessert. In northern Vietnam, it is known as bánh caramel, kem caramel or caramen and in southern Vietnam, it is known as bánh flan or kem flan. The difference between Vietnamese flan and European flan is Vietnamese flan is usually smaller and steamed rather than baked. Vietnamese flan also uses coconut as an ingredient and is drizzled with black coffee when served.
