Egg Custard Tarts are a popular sweet treat in dim sum restaurants. These tarts consist of a flaky pastry crust filled with a smooth and creamy egg custard. The custard is made with a mixture of eggs, sugar, milk, and vanilla extract, resulting in a rich and velvety texture. The pastry crust is made with a combination of flour, butter, and sugar, creating a delicate and buttery base for the custard. Egg Custard Tarts are typically baked until the custard is set and the crust is golden brown. The combination of the sweet and creamy custard with the buttery and flaky crust makes these tarts a delightful ending to a dim sum meal.
