What do early 19th century Portuguese Monks do when they need to earn a steady income? They learn to bake and sell pastries. And none is so famous as the Pastéis de Nata egg pastry that may be found in nearly every bakery and coffee shop in Lisbon. Crispy on the outside, sweet and creamy on the inside, the pastel de nata is a local treasure. Hot out of the oven they are at their best. Dusted with a bit of powdered sugar and cinnamon, the monks knew centuries ago that they had stumbled on to something divine.
