Le Strade della Mozzarella (LSDM) is one of the first Italian food festivals and the one dedicated specifically to mozzarella. It is held annually in the ancient city of Paestum, south of Naples, the land of mozzarella di bufala. And now it is going international: it has established editions in Paris, Geneva and London. This coming May LSDM will be in New York—say the two founders, Barbara Guerra and Alberto Sapere.
