Characterized by its round, elongated shape, this sweet Portuguese treat combines buttery pastry and a creamy, cinnamon-spiced egg yolk filling. The name of the pastry is linked to campinos - traditional cattle herders who use long wooden sticks (pampilhos) to encourage cattle to move.

Although it is found in other Portuguese regions, pampilho is traditionally associated with Santarém. It is typically enjoyed for breakfast or as a sweet mid-day snack.
