Egg custard tarts are a sweet dim sum treat that can be made using a food processor. The tart crust is made by blending flour, butter, sugar, and egg in the food processor until a dough forms. The dough is then rolled out and pressed into tart molds. The custard filling is made by whisking together eggs, sugar, milk, and vanilla extract. The custard is poured into the tart shells and baked until set. The result is a golden and creamy egg custard tart with a buttery crust.
