Italian sausages are fresh pork sausages that include those in the style of northern Italy, which are sweet and mild, and sometimes flavored with fennel seed. Southern-style sausages, such as Neapolitan varieties, are often flavored with dried chili pepper flakes and tend to be hot.
For other sausage types, see andouille, Chinese, chouriço, and chorizo, linguiça, loukanika, and mortadella.
