The Pasteis de Belém bakery in Belém, the southwestern most civil parish of the municipality of Lisbon. In 1837 they began making the original Pastéis de Belém, a Portuguese egg tart pastry dusted with cinnamon, following an ancient recipe from the Mosteiro dos Jerónimos, Jerónimos Monastery or Hieronymites Monastery. That recipe, kept secret, is recreated every day in the bakery, by hand, using only traditional methods. In other parts of Portugal attempted copies are called Pastel de nata.
