Portuguese Pastéis de Nata are small, creamy custard tarts that originated in Portugal. They feature a flaky, crispy pastry shell filled with a rich custard made from eggs, sugar, and cream. Traditionally, they are baked at high temperatures, resulting in a caramelized top and a warm, soft interior. These delightful treats are often enjoyed with a sprinkle of cinnamon or powdered sugar on top. Pastéis de Nata are popular not only in Portugal but also in many countries around the world, where they are celebrated for their unique flavor and texture.
