Egg custard tarts are a classic dim sum dessert that is loved by many. These tarts consist of a flaky pastry crust filled with a smooth and creamy egg custard. The custard is made from a mixture of eggs, sugar, milk, and vanilla extract, which is then baked until set. The result is a sweet and rich tart with a delicate texture. Egg custard tarts are often served warm and can be enjoyed as a sweet treat at the end of a dim sum meal. They are a must-try for anyone with a sweet tooth.
