Pastéis de Belém, a popular tourist spot, attracts locals with its charming blue and white interior. The history of the famous pastel de Belém dates back to 1834 when the Mosteiro dos Jerónimos first sold sweet pastries. Their success led to the official production of Pastéis de Belém three years later in 1837, following the unchanged secret recipe. Pastéis de Belém claims to be the originator of the egg tart, known as pastel de nata (cream pastry) in Portugal. The egg tart features a salty, buttery crust and a luscious filling resembling light custard, topped with a distinctive charred surface.
