Fabrica de Pasteis de Belem is a historic bakery in Lisbon, Portugal, notable for producing the original pastel de nata — the traditional Portuguese egg-custard tart — using a centuries-old recipe first devised by the monks of the nearby Jeronimos Monastery. The pastries are served warm, with a crisp, flaky crust and a smooth, creamy custard filling that preserves the character of the monastery's original creation. - AsNotedIn
