The origin of Gelataria Portuense is not your average love story. It is a more intricate tale, worthy of the universe of writer Isaac Asimov, as it begins with a woman's passion for a machine. In this case, the woman is the Porto-based gelatiere Ana Castro Ferreira, and the device is called Effe, a prodigious gelato machine created at the hands of Otello Cattabriga, an ingenious and talented Italian inventor. When Ana – who formerly worked as a researcher on sustainable energy systems for buildings – took an interest in gelato, she went about searching for a gelato-making class. While investigating online, Ferreira came across a video in which skilled hands demonstrate the agility and elegance of the Effe machine.
