25. Somerville, Massachusetts — What the Fluff? Festival
Somerville’s Union Square has celebrated the important invention of marshmallow fluff with its What the Fluff? Festival each year since 2005.
The city takes credit for the 1917 invention (although there’s been some debate over the true origins of fluff) and commemorates the “spirit of innovation” at this festival.
The 2021 event saw delightful, sugary confections such as fluff-fused momos, churros, macaroons and whoopie pies, reports Boston.com. And Himalayan Kitchen, known for its dumplings, came up with “flufflings” instead — offering pineapple and ricotta fluff flavors.
