The history of Vietnamese flan, known as Banh Flan, is intertwined with Vietnam's colonial past. Introduced during the French colonial period, Banh Flan reflects the influence of French cuisine on Vietnamese culinary traditions. The French brought the concept of creme caramel made with whole eggs or egg whites, which eventually merged with local ingredients and flavors to create the Vietnamese adaptation. While it maintains the essence of the classic French flan, Vietnamese flan stands out with its use of either coconut milk, or sweetened condensed milk providing a distinct tropical twist. Today, Banh Flan is cherished as a delectable fusion of French and Vietnamese culinary heritage, showcasing the country's cultural diversity on the dessert plate.
