Egg custard tarts are a popular dessert at dim sum restaurants. These sweet treats consist of a flaky pastry shell filled with a smooth and creamy egg custard. The custard is made with eggs, sugar, milk, and vanilla extract, and it is baked until set. The pastry shell is buttery and crisp, providing a perfect contrast to the creamy custard filling. Egg custard tarts are often served warm, and they are best enjoyed with a cup of tea. They are a delightful way to end a dim sum meal, and they are also great for afternoon tea or as a sweet snack.
