SlowFood recently posted an interesting article titled Glimpses and Smells: Recipes and Short Films, based on an interview of Diana Maria Tohătan (a Romanian immigrant to Italy, who prepared food for the Migranti Film Festival, held at the University of Gastronomic Sciences campus in Pollenzo and in Bra in June 2018. Among the quotes is this: “Food is a primary need, it’s the easiest way to start an intercultural dialogue” which shows the relevance of this article for followers of this site.
