The Portuguese egg tart, known as pastel de nata, is a popular pastry originating from Portugal. It features a flaky, crispy crust filled with a creamy custard made from eggs, sugar, and milk. The top is often caramelized to a golden brown, giving it a slightly charred flavor. These tarts are typically served warm and can be enjoyed plain or dusted with cinnamon and powdered sugar. They are a staple in Portuguese cuisine and have gained international popularity, often found in bakeries and cafes around the world.
