Portuguese Tarts (Pastéis de nata) date back to pre 18th century and the monks at the Jerónimos Monastery in the parish of Santa Maria de Belém in Lisbon. At that time, convents and monasteries used large quantities of egg-whites for starching clothes. Famed for their pastries, the Portuguese Tart was created to use up the yolks in a custard. They are a staple part of the Portuguese diet and are eaten at all times of the day. With a touch of cinnamon, they are great for festive occasions.
This recipe makes 1.5 litres of custard – enough for 60 tarts.
