Chicago Mix popcorn is one of the city's most iconic foods, but what exactly is it, and who lays claim to the sweet-and-savory treat's origins?

National Today surveyed 1,000 Americans about their popcorn-eating preferences and found that the top three flavors are butter, cheddar, and caramel. So we ordered these flavors from each brand.

Chicago-based Garrett Popcorn makes nine different flavors, but the Garrett Mix — that combination of caramel and cheese — is the company’s best seller, said Garrett co-owner Megan Chody.
