Pastéis de Nata, also known as Portuguese custard tarts, are a famous Portuguese pastry. These delicious tarts consist of a flaky pastry shell filled with a creamy custard made from eggs, sugar, milk, and vanilla. The tarts are baked until the custard is set and the pastry is golden brown. Pastéis de Nata are best enjoyed warm, sprinkled with cinnamon and powdered sugar. They are a true delight and a symbol of Portuguese cuisine.
