Over 250 years ago in a monastery in the hills of Lisbon, a sinfully delicious dessert was created by the mostly heavenly nuns: a thin puff pastry shell filled with sinfully smooth custard made from the very best and wholesome ingredients. So creamy, delicious and enticing was this creation that it traveled the sea, transcended ethnic boundaries and has claimed the desire of dessert lovers throughout the continents. The Pastel de Nata or Portuguese Custard Cup is the perfect combination of crispy crust and smooth creamy custard decorated with dark caramelized spots.
