Egg Custard Tarts are a popular dessert in dim sum cuisine. These tarts have a buttery and flaky pastry crust filled with a smooth and creamy egg custard. The custard is made with a mixture of eggs, milk, sugar, and vanilla extract. The tarts are baked until the custard sets and the crust turns golden brown. Egg Custard Tarts are best enjoyed warm and are a delightful way to end a dim sum meal.
