A Time of Angels by Patricia Schonstein

Primo Verona is born with a gift of clairvoyance so strong that he is able to predict his own mother's death while still in her womb. Brought up on a rich diet of astronomy, philosophy, and storytelling, Primo accurately reads the futures of the local community who pay him in honey cake, tiramisu, and other delicacies. Pasquale Benvenuto is the owner of a beloved wine bar and delicatessen whose culinary reputation rests on recipes for the fruited breads and salamis his father taught him to make.

Together Primo and Pasquale form an easy friendship triangle with the beautiful Beatrice, Primo's wife and Pasquale's former girlfriend. But when Beatrice leaves her husband for her old love, Primo is devastated. He casts spells to spoil Pasquale's creations and to win back Beatrice -- but inadvertently conjures up an unexpected visitor.
