Even though it's hard to pinpoint the exact point in time when Fenway franks were invented, it is believed that they were first sold soon after the park's 1912 opening. Since then, these delicious hot dogs have become popular fan favorites at baseball games and a true Boston staple.

Unlike other ballpark hot dogs which are typically either grilled or steamed, Fenway franks are boiled and grilled, then placed in a split bread roll and consumed plain or topped with various relishes or mustard. This hot dog variety is characterized by its bold flavors because the meat is flavored with garlic, onion, and mustard, and the sausages are then cooled using a special process in order to preserve the juiciness.
