A factory in Cambridge makes 14 million Junior Mints a day. Why is no one allowed inside?

On the walk from Kendall Square into Central Square, you’ll pass the last remaining candy factory in Cambridge. It’s a boxy cream-colored building, with opaque windows. A small sign out front whispers that the facility, Cambridge Brands, is owned by Tootsie Roll Industries. You need sharp eyes to read it from the far side of Main Street.

For a few years now, I’ve wanted to unwrap the mystery of the Cambridge Brands factory, and find a way to get inside. I succeeded at one of those goals.

My starting point: Everyone in Cambridge assumed that the factory probably made Tootsie Rolls or Tootsie Pops — or maybe both — given its corporate parentage. And the small sign incorporates Tootsie’s familiar white, red, and brown color scheme.
