Egg tarts are a beloved dim sum dessert that can be made effortlessly with the Thermomix. The tart shells are made with a simple pastry dough that is filled with a smooth and creamy egg custard. The tarts are then baked until the custard is set and the crust is golden brown. These bite-sized treats are a perfect balance of sweet and savory, making them a delightful addition to any dim sum spread.
