It is a rarity of unique taste, a treat to serve on tables. The onion confit with PGI Modena’s balsamic vinegar is a particular kind of marmalade characterized by bitter-sweet notes and an intense brown-purple color. This sauce is ideal with cheese, glorifying the taste, without overpowering the flavor or in combination with various types of meat. A suggestion: try it with “Lardo di Colonnata” or with a special Prosciutto crudo di Parma.
