Also, unique in Canada, Jacks Pastéis de Tentúgal are Portuguese pastries that originated in Tentúgal, a tiny town halfway between Lisbon and Porto. These pastéis, created by Carmelite nuns in the 16th century, are packets of thin, flaky pastry filled with a rich egg custard and dusted with powdered sugar. They were crispy and buttery and eggy and just the right amount sweet.
