Red Snapper (Lewiston, Maine)

Particularly common in Maine, these small natural-casing beef and pork hot dogs are snappy, all right, as well as red – dyed neon-red, for reasons that probably have to do with marketing. Typically they're served with bright yellow mustard, lobster roll style: in a New England split-top bun, steamed or lightly toasted (and sometimes buttered).

Where to Get It: For more than a century, Simone's Hot Dog Stand has done red snappers right: a Jordan's dog steamed and picturesquely drizzled with mustard (and optional celery salt), atop a bed of relish and onions in a steamed roll. 99 Chestnut St., Lewiston, ME
