Pastéis de Belém.... mmmmm....

I'm suddenly missing Pastéis de Belém (pash-TEISH de buh-LEHNG). According to my guidebook, the original recipe for pastel de nata is a closely guarded secret. I love and remember the creamy egg tarts sold as "Portuguese tarts" in bakeries in Singapore, but this is THE original Portuguese tart, sold in its beautifully tiled coffee shop in the neighborhood of Belém, about 20 minutes' bus ride from central Lisbon. The pastry is flaky, and each flake is crispy. Dusted with icing sugar and cinnamon, it is to die for! At just 0,80 euros a piece, how many can you eat?
