One of San Francisco's oldest and longest-standing food markets is Molinari, which has been around since 1896. Since then, Molinari has been making some of the tastiest salamis and selling Italian groceries at their market in North Beach.
Molinari distributes their salamis locally throughout the Bay Area. I'm particularly enamored with their Finocchiona salame, which is a dry-cured pork salami with fennel seeds. They also make sopressata, hot salame, coppa, pancetta, and sausages.
The store in North Beach sells all kinds of prepared Italian foods, sandwiches, Italian wines, olive oil, pasta, cheese, and other Italian delicacies. If you're looking for an Italian food ingredient, you'll most likely find it at Molinari.
